Question

The age of uzair is 10 years 8months and the age of usman is 13 years 4 months. find the ratio between their ages in the lowest form?​​​

Answer 1

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)
