Question

Divide £32 in a ratio of 3:7

Answer 1

`3x+7x=\pounds32\\ 10x=\pounds32\\ x=\pounds3.2\\ 3x=3\cdot\pounds3.2=\pounds9.6\\ 7x=7\cdot\pounds3.2=\pounds22.4\\\\ \boxed{\pounds9.6 \text{ and } \pounds22.4}`

Answer 2

`3 + 7 = 10`


`32` ÷
`10 = 3.2`


`3.2` ×
`3 = 9.6`


`3.2` ×
`7 = 22.4`

£9.60 : £22.40
