The ratio of the ages of Kissi and Esinam is 3:5 and that of Esinam and Lariba is 3:5 and the sum of the ages of all 3 is 147 years, what is the age difference between oldest the youngest

The age difference between oldest the youngest is of 48 years.

Step-by-step explanation:

We can solve this question using a system of equations.

I am going to say that:

Kissi's age is x.

Esinam's age is y.

Lariba's age is z.

The ratio of the ages of Kissi and Esinam is 3:5

This means that , so

That of Esinam and Lariba is 3:5

This means that , so

The sum of the ages of all 3 is 147 years

This means that

What is the age difference between oldest the youngest

z is the oldest

x is the youngest.

First i will find y.

We have that, from the equations above: and

So

The lesser common multiple between 5 and 3 is 15. So

Youngest:

Oldest:

Difference:

75 - 27 = 48

The age difference between oldest the youngest is of 48 years.

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8
