### Unit 2 - Fractions Help

Help help help... I have got to task 6 of the fractions the ones where you have to mix the sums together and I am on SAQ 6 and I cannot for the life of me get past letter d where the fractions turn to addition and subtractions I am pulling my hair out. I have scanned the Internet and all the recommended sites and still cannot get it. Can somebody help me before I go bald???

### Re: Unit 2 - Fractions Help

Hi,

For these types of questions it is important to realise that you just take them as simple sums according to the order of calculations or Bidmas.

So for part e) we have 1 2/3 + 7/8 - 3/4

Using the order of calculations we would do the addition first and then the subtraction. So we do

1 2/3 + 7/8 first

This is the same as 5/3 + 7/8

We need a common denominator so we use 24 here

5/3 = 40/24 and

7/8 = 21/24

So 5/3 + 7/8 = 61/24

Now we do the subtraction so we have 61/24 - 3/4

Again we need a common denominator so we use 24

3/4 = 18/24

Now we have 61/24 - 18/24 = 43/24 which simplifies to 1 19/24

Hope this helps you,

Yvonne
