Question

Rolando's Labrador retriever had 12 puppies. Eight of her puppies were yellow labs and the rest were black labs. What is the ratio of the number of black lab puppies to the number of yellow lab puppies?

Answer 1

1:2

Explanation:

There are 12 total puppies. To find the number of black puppies, we have to subtract the yellow from the total. So:

12 - 8 = 4

There are 4 black puppies. Now we put the black puppies in ratio to yellow puppies:

4:8

Then simplify (divide both sides by 4):

1:2

Answer 2

2:1

Explanation:

12 = total

yellow labs : black labs

8 : 4

simplified version is 2:1
