Help due soon please help

uncle Alan age 48  and cousin Lisa age 24

aunt Marengo age 42  and cousin dale age 21

uncle Brad age 36  and cousin Kan age 18

Step-by-step explanation:

Firstly, the age ratio of  crystals and Alexa should be computed to know the ages of the family member pair that have same ratio.

The age of Crystal is 12 years and the age of Alexa is 6 years. The fraction of their age is  12/6  = 2/1. So the ratio of Crystal age to Alexa age is 2:1. We have to find the family member pair with ratio of 2:1.

uncle Alan age 48  and cousin Lisa age 24 have same ratio. 48/24 = 2/1 = 2:1

aunt Marengo age 42  and cousin dale age 21  have same ratio . 42/21 = 2/1 = 2:1

uncle Brad age 36  and cousin Kan age 18  have same ratio. 36/18 = 2/1 = 2:1
