Question

Divide £32 in a ratio of 3:7

Answer 1

3 +7=10
32÷10=3.2
3.2×3=9.6
3.2×7=22.4
=£9.60:£22.40

Answer 2

First part of £32 is £9.6 and second part of £32 is £22.4.

Explanation:

We need to divide £32 in a ratio of 3:7.

Let the first part be 3x and second part by 7x.

The sum of ratio is

`3x+7x=32`

`10x=32`

Divide both sides by 10

`x=(32)/(10)`

`x=3.2`

The value of x is 3.2.

First part of £32 is

`3x=3(3.2)=9.6`

Second part of £32 is

`7(3.2)=22.4`

Therefore first part of £32 is £9.6 and second part of £32 is £22.4.
