Answer:

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:

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
