Question

There are 45 carpenters in a crew. 18 of the carpenters have children. What is the ratio of the number of carpenters to the number of carpenters who do not have children? Write the ratio simplified.

Answer 1

Answer is 5:3

==========================================================

Step-by-step explanation:

There are 45 carpenters total. 18 have kids, so 45-18 = 27 do not have kids.

The ratio of the total to the number who don't have kids is 45:27. We write the numbers in the exact order mentioned. Divide both parts of that ratio by the GCF 9 to get the final answer of 5:3

This says that for every 5 carpenters total, there are 3 who don't have kids.
