Question

At camp in Green Bay, Wisconsin, 7/9 of the participants were from Wisconsin. Of that group 3/5 were 12 years old. What fraction of the group was from Wisconsin and 12 years old?

Answer 1

7/15

Explanation:

It means that the number of participants from Wisconsin is a subset of the number of people in the camp. Furthermore, a percentage of the participates from Wisconsin are 12 years old.

The product of the fraction of the participants in the camp that are from Wisconsin with the fraction of that group that were 12 years old will give us the fraction of the group that were from Wisconsin and were 12 years old.

fraction of the group was from Wisconsin and 12 years old

= 7/9 * 3/5

= 21/45

= 7/15

Answer 2

Since the problem stated that 7/9 of the participants were from Wisconsin, so 2/9 of it were not from Wisconsin. Now out of 7/9 participants, 3/5 of them were 12 years old, so 2/5 of them are not 12 years old. Since we now know the fractions, we'll get the equation 7/9 x 3/5 multiply 7 and 3 then divide it to the product of 9 and 5 to have the answer of 7/15. 7/15 of the participants of the camp in Green Bay is from Wisconsin and are 12 years old.
