Answer: 0.249
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
We can think of 24.9% as the ratio 24.9 to 100 or 24.9 ÷ 100.
Remember that dividing by 100 moves the decimal point two places to the left so 24.9 ÷ 100 will move the decimal point two places to the left which would give us .249 or 0.249.
Therefore, 24.9% can be written as the decimal 0.249.

Answer: The average age is 7.1 years.
This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.
To start, lets multiply the total number of children by their individual ages.
6 x 5 = 30 years
14 x 8 = 112 years
There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.
