Adding Fractions
How to add fractions with different denominators
Like 2 1/4, 3 5/8
Its a whole number with fractions

Re: Adding Fractions
I would turn each into an improper fraction then add the two improper fractions together using a common denominator. Then turn the answer back into a mixed fraction if required.
Is this an 11+ topic?

Re: Adding Fractions
Can your child add fractions with different denominators, using the concept of equivalent fractions? Can he/she add 1/4 and 5/8 by turning the 1/4 into 2/8?haniya11plus wrote:can someone reply with easy steps or 9 years old please
The whole numbers should look after themselves.

Re: Adding Fractions
Change 2 1/4 into eighths.
Then it should be straightforward to add the two fractions together.

* recognise mixed numbers and improper fractions and convert from one form to the other and write mathematical statements > 1 as a mixed number (e.g. 2/5 + 4/5 = 6/5 = 1 1/5)
* add and subtract fractions with the same denominator and multiples of the same number
Wait until it has been taught in school.

Re: Adding Fractions
I think you have more fundamental maths problems to address first. A week ago your daughter was 10.haniya11plus wrote:yes , its 11+ topi

Re: Adding Fractions
Hello Haniya,
I have tried to give a little breakdown if it helps your child.
2 1/4 + 3 5/8
a) turn each part into improper fraction
2 1/4 = ((2x4)+1)/4 = 9/4
3 5/8 = ((3x8)+5)/8 = 29/8
b) now add each improper fraction by making a common denominator
9/4 + 29/8 = 18/8 + 29/8 = 47/8
c) convert the answer back to proper fraction
Dividing 47 by 8 gives quotient of 5, and leaves a remainder of 7
47/8 = 5 7/8
OR
You could simply add the whole numbers separately and fraction part separately
2 1/4 + 3 5/8
(2+3) + (1/4 + 5/8)
5 + (2/8 + 5/8)
5 + 7/8
47/8 = 5 7/8
