15 years 3 months and 14 years 8 months. Find the average age per girl in the group​

Answer 1

Answer:

15 years 4 months

Step-by-step explanation:

We have always learned that comparison is done only when the things compared are in the same unit. So, we will do the same here i.e. we will convert all of the ages to months only!

For the age of 2nd girl of the group:

15 years 8 months

= ( 15 * 12 ) + 8 months

= 180 + 8 = 188 months

For the age of 1st girl of the group:

16 years 4 months

= ( 16 * 12 ) + 4 months

= 192 + 4 = 196 months

For the age of 3rd girl of the group:

14 years 9 months

= 14 * 12 + 9 months

= 168 + 9 = 177 months

For the age of the 4th girl of the group:

15 years 3 months

= ( 15 * 12 ) + 3 months

= 183 months

For the age of 5th girl of the group:

14 years 8 months

= ( 14 * 12 ) + 8

= 168 + 8 = 176 months

Calculating the average age:

( 188 + 196 + 177 + 183 + 176 ) ÷ 5

= 920 ÷ 5

= 184 months = 180 months + 4 months

= 15 years 4 months
