Answer 1

Answer:

the younger brothers age will be 14 yrs and te ratio 7 yrs later will be 4:3

Explanation:

if we take the age of the younger brother to be x and we have to find x the equation will be 3/2=21/x.

when we solve it we will get x=14 so the younger brothers age is 14yrs

now 7yrs later older brothers age will be 21+7=28 and younger brothers age will be 14+7=21

so the ratio 7 yrs later will be 28/21 and when we simplify it becom s 4/3=4:3
