Question

Divide £300 in a ratio of 3:7

Answer 1

Ratio is:
$3:7$
it means you have to sum
$3+7=10$
Now you have to divide $300$ by $10$
$300/10=30$
Now multiplay
$3*30=90$
and
$7*30=210$
so £$300$ in ratio $3:7$ will be $90:210$

Answer 2

1. Add 3 + 7 = 10

2. Divide 300 by 10 = 30

3. Times 30 x 3 = 90

4. Times 30 x 7 = 210

90 + 210 = 300

your answer is 90 : 210
