At the city park there were 15 blue jays, 6 cardinals, and 9 mockingbirds.

For each of the following questions set up a proportion equation and solve for the unknown.

1. If there were 6 mockingbirds, how many cardinals would there be at the park?

2. If there were 5 blue jays, how many cardinals would there be at the park?

3. If there were 20 cardinals, how many mockingbirds would there be at the park?

Answer 1

At the city park there were 15 blue jays, 6 cardinals, and 9 mockingbirds.

6 mockingbirds is 2/3 of 9
so 2/3 of 6 is 4 cardinals

5 blue jays is 1/3 of 15
so 1/3 of 6 cardinals is 2 cardinals

There are 20 cardinals, how many mockingbirds.
the ratio is 2/3, so 20/30 is your answer

hope this helps
