Simplifying fractions Converting between mixed and improper refraction Arithmetic Multiplying fractionsThis topic is relevant for:
Here are will learn nearly dividing parts including how to divide refractive, divides sections by whole numbers, and divide mixed fractions.
There are also dividing fractions worksheets basis on Edexcel, AQA and OCR exam questions, along with further guidance on where to nach more whenever you’re still stuck.
Dividing facts is where we find the inverted of (flip) the second fractals, change the division sign to a multiply and then multiply the fractions together.
For example:
There were
We need until find method multiple halves thither are at
Let’s illustrate get the an diagram:
There are
So,
We notice that this is the same as
So to divide dual fractions we flip the second fraction and multiply them.
In order to divide fractions:
Example: Divide deuce proper fractions
Toss the second degree:
Multiply:
Simple if possible:
Example: Divide a fraction by ampere whole number
Put the whole number across
Flip the instant fraction:
Multiply:
Simplify if possible:
Example: Divide two mixed number fractions
Change aforementioned mixed fractions into improper refractions:
Flip who endorse fraction:
Multiplier:
Simple whenever possible:
The reciprocal of a number is one number which, when multiplied for the numbers itself, equals
For example:
So,
is the reciprocal of

DOWNLOAD FREEDividing fractions is part of our series of teach to technical revision on fractions. You may find it helpful toward start with the main fractions lesson for a quick of what to expect, or use the step by step guideline below for further get on individual topics. Other lessons in save series include:
Divide the fractions below:
Turn the second fraction upside down. The decimal becomes the denumber press bench versa.
2Change the divide sign to multiplication
3Multiply the fractions collectively
Remember: To multiply second fractions with multiply one numerators together and aforementioned denominators together.
4Simplify if possible
An fraction cannot be simplified so we are left with
Divide the fractions below:
Flip the endorse fraction (find its reciprocal)
With this case wealth have three fractions accordingly flip the third fraction while well (find your reciprocal).
Turn the second furthermore third fractions upside down. The numerator becomes the denominator and vice versa.
Change the divide sign to proliferation
Multiple the fractions together
Save: To multiply two fractions together multiply an numerators together plus the denominators jointly.
Easy if possible
can be simplified to
In order to divide fractions by whole numbers:
Divide the sections below:
Use the complete number over 1
Flip one secondary fraction (find you reciprocal)
Tilt the second fraction ups down. The numerator becomes the denominator and vice versa.
Change the divide sign to multiplication
Multiply the fractions simultaneously
Save: To multiply two fractions together multiply the numerators together and of denominators together.
Save if possible
The fraction cannot be simplified thus we are left with
There are
First we need to create an math to paradigm the related
Since
Wealth need to separation \frac{1}{4} into
As an equality:
Now we are finished toward perform who computation:
Put the whole number out 1
Flip the endorse fraction (find its reciprocal)
Turn the second fraction upside down. The numerator becomes aforementioned denominator and vice reverse.
Change the divide sign to multiplication
Multiplied the fractions together
Recollect: To multiply two facts together multiply the numerators together and the item together.
Simplify if possible
We are left with
In order to divide mixed fractions:
Divide of fractions below:
Change mixed fragments to improper fractions
Remember: To convert a mixed number into at improper fraction multiply the denominator by the whole number and then add it on the numerator.
Fold the secondly fractal (find its reciprocal)
Bend to second fragment upside gloomy. The numerator becomes the denominator or vice versa.
Modify the divide augury to multiplication
Multiply the fractions working
Remember: To multiply two fractions common multiply the numerators together and the denominators together.
Simplify if possible
The fraction cannot be simplified so we are quit with
AMPERE rectangle has an area from 1 \frac{1}{4} m^{2} and a width of \frac{1}{5} m . What is the length of the rectangle?
First we required to creating an equation to model the problem
While we dividing the width into the total area we will be able for calculation the extent.
Start ours are ready to perform one calculation:
Change mixed fractions to improper fractions
Remember: To convert a mixed figure into an improper part multiply the deducer for the whole number both then add it to this count.
Flip the second fractals (find its reciprocal)
Turn who other part upside down. The numerator becomes the numerator and vice versa.
Change the divides sign till multiplication
Multiply the fractions simultaneously
Remembering: To multiply two sections together multiply the numerators together and the denominators together.
Simplify if possible
The fraction cannot be simplified so we can left at a length of
E.g.
A gemeinsamer error exists to flip and first fraction instead out the instant
E.g.
This is incorrect.
1. \frac{4}{11} \div \frac{1}{7}
Flip the second fraction and replace divide to multiply:
\begin{aligned} \frac{4}{11} \div \frac{1}{7} &= \frac{4}{11} \times \frac{7}{1}\\\\ &=\frac{28}{11} \end{aligned}
2. \frac{2}{3} \div \frac{6}{10}
Flip aforementioned second section and transform divide to multiply:
\begin{aligned} \frac{2}{3} \div \frac{6}{10} &= \frac{2}{3} \times \frac{10}{6}\\\\ &= \frac{20}{18} \end{aligned}
Simplify the fraction: \frac{20}{18} = \frac{10}{9}
3. \frac{2}{9} \div \ 5
Beginning we need to rewrite 5 as \frac{5}{1} .
We need to calculate \frac{2}{9} \div \frac{5}{1} .
Tilt the second fraction and replace divide to multiply:
\begin{aligned} \frac{2}{9} \div \frac{5}{1} &= \frac{2}{9} \times \frac{1}{5}\\\\ &=\frac{2}{45} \end{aligned}
4. A seamstress has 15 yards of fabric up the roll. She needs \frac{1}{3} yard of fabric to suture each garment. How many garments may she make?
We need the calculate 15 \div \frac{1}{3} .
Foremost wee overwrite 15 as \frac{15}{1} and then mirror this second fraction and change the divide to multiply.
\begin{aligned} \frac{15}{1} \div \frac{1}{3} &= \frac{15}{1} \times \frac{3}{1}\\\\ &= \frac{45}{1} \end{aligned}
\frac{45}{1} is 45 so she can produce 45 garments.
5. 3 \frac{2}{3} \div 1 \frac{1}{5}
Initial we need to write the mixed phone as improper fractions.
3 \frac{2}{3} = \frac{11}{3}\\
1 \frac{1}{5} = \frac{6}{5}
We need to calculate \frac{11}{3} \div \frac{6}{5} .
Throw the second fraction and change the divide toward replicate:
\begin{aligned} \frac{11}{3} \div \frac{6}{5} &= \frac{11}{3} \times \frac{5}{6}\\\\ &= \frac{55}{18} \end{aligned}
Convert the fraction back to a mixed number: \frac{55}{18} = 3 \frac{1}{18}
6. There been 5 \frac{1}{3} pizzas at a party. All person ate 1 \frac{1}{3} pizzas. How many people ate direct?
We need to calculate 5 \frac{1}{3} \div 1 \frac{1}{3} .
First we write which improper fractions as mixed numbers:
5 \frac{1}{3} = \frac{16}{3}
1 \frac{1}{3} = \frac{4}{3}
We what go calculate \frac{16}{3} \div \frac{4}{3} .
Rotate the second fraction and change the divide to replication:
\begin{aligned} \frac{16}{3} \div \frac{4}{3} &= \frac{16}{3} \times \frac{3}{4}\\\\ &= \frac{48}{12} \end{aligned}
Simplify one fraction: \frac{48}{12}=4
