Question

The ratio of Jay age to Hena's age to Sally age is 4:3:6.Jay is 24 years old

(a)Find Sally's age.
(b)What is their total age?​

Answer 1

Sally is 36 years old.

their total age is 78 years.

Explanation:

`4 + 3 + 6 = 13`

that's the total ratio

Jay is 24 years old and his ratio is 4

so assume the total age to be

`x`

`4 / 13 * x = 24`

`4x / 13 = 24`

`4x = 24 * 13 / 4`

`x = 78 \: total \: age`

t

`sally \: age = 6 / 13 * 78`

`sally \: is \: 36years \: old`

Answer 2

1. Write It Out:

Jay 4: Hena 3 : Sally 6

Jay is 24 years old.

2. Solve

So first you find 24/4 to get 6. This means Jays age was divided by 6 to get his ratio number. Showing that Hena's and Sally's is divided by 6 as well to get there ratios. Now what you need to do is mulitipy Hena and Sallys ratio by six to find there age's.

Hena: 3x6= 18 years old

Sally: 6x6= 36 years old

(Jay: 4x6= 24 years old)

Now to find there total age add them up...

18+36+24= 78

A. Sally is 36

B. 78
