Answer:
The ratio of Jay's age to Kiaria's age to Martha's age is 1: 2 : 4.
Step-by-step explanation:
Here, let us assume the age of jay = u years
So, the age of Kiaria = Age of Jay + 7 = u + 7
And, the age of Martha = 2 x ( age of Kiaria) = 2 ( u + 7)
Now, the sum of the ages = 7 u
⇒ (u) + (u + 7) + 2 ( u + 7) = 7 u
or, u + u + 7 + 2 u + 14 = 7 u
or, 4 u + 21 = 7 u
⇒ 3 u = 21 or u = 21/3 = 7
⇒ u = 7 years
Hence, the age of Jay = m = 7 years
Age of Kiaria = m + 7 = 7 + 7 = 14 years
Age of Martha =2 ( m+7) = 2 ( 7 +7) = 28 years
So, the ratio of Jay's age to Kiaria's age to Martha's age
is 7: 14: 28 = 1: 2 : 4
Hence, the final ratio of the ages is 1: 2 : 4.
