David, Stephen and June share £96 in a ratio 2:3:3. How much money does each person get
AveGali [126]

Answer:

<u>David gets £24, Stephen gets £36, and June gets £36.</u>

Step-by-step explanation:

Firstly, add the ratio values together.

2:3:3  ⇒  2 + 3 + 3 = 8

Next, divide £96 (your total) by 8.

£96 ÷ 8 = £12

Now, we have the number of pounds for 1 value.

Multiply 12 by each ratio value.

<u>12 × </u><u>2</u> : <u>12 × </u><u>3</u> : <u>12 × </u><u>3</u>

= 24:36:36

Therefore, David gets £24, Stephen gets £36, and June gets £36.
