Step-by-step explanation:
A/B=1/3 ;
A=B -5; or B=A+5 ;
A/B=1/3 ; or A/A+5=1/3
3A=A+5 ; or A=2.5
B=2.5*3=7.5
In other words, A’s age =2yr 6 month.
B’ age =7 yr 6 month □ANSWER.

Answer:
The ages if a and b are respectively 2.5,7.5
Step-by-step explanation:
Given,The ratio of the ages of A and B is 1:3
The difference between the ages of the A and b is 5
to compare 1x:3x
3x-5 = 1x
3x-1x= 5
2x= 5
x = 5/2=2.5
The age of A is 2.5 years
The age of B is (2.5)×3 = 7.5
