Solution:
As 1 year = 12 months
Age of Uzair = 10 years, 8 months
= 10×12 months+8 months
= 120 months+8 months
= 128 months
Age of Usman = 13 years, 4 months
= 13×12 months+4 months
= 156 months+4 months
= 160 months
Ratio between two ages = 128 : 160
= 128 : 160 (÷ by 2)
= 64 : 80 (÷ by 4)
= 16 : 20 (÷ by 4)
= 4 : 5
Ratio between two units = 4 : 5 (ans)
