Question from jennifer, a student: Tina is older than Catherine by 1 year and 7 months. Karen is younger than Tina by 2 years and 11 months. If Karen is 7 years and 2 months old, find out Catherine's age. |
Hi Jennifer,
I can help get you started.
Since Karen is younger than Tina by 2 years and 11 months, Tina is older than Karen by 2 years and 11 months. Karen is 7 years and 2 months old so if you add 2 years and 11 months to 7 years and 2 months you get 9 years and 13 months. But 12 years makes a year so Tina is 10 years and 1 month old.
How old is Catherine?
