Question

uma is 12 years 9 months 5 days old. her brother is 10 months 1 day old. how much older is uma than her brother?

Answer 1

Uma is 11 years 11 months 4 days older

Explanation:

Given

Let

x = Uma's age

y = Her brother's

So:

x = 12years 9months 5days

y = 10 months 1 day

Required

How much older is Uma

To do this, we simply calculate the difference (d) in their ages:

`d = x - y`

This gives:

d = [12 years 9 months 5 days] - [10 months 1 day]

Collect like terms

d = [12 years 9 months - 10 months] + [5 days - 1 day]

d = [11 years 11 months] + 4 days

d = 11 years 11 months 4 days
