The ratio of dogs to cats at the pet store is 3 : 4. There are 21 total pets. How many cats are in the pet store? Hint: you may want to make a tape diagram.

12 cats

Step-by-step explanation:

first add 3 and 4 together to get 7

divide 21 by 7 to get 3

if there are 4 cats out of 7 pets in the store, you should be able to multiply 4 by 3 to get the total amount of cats in the whole store to get 12

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
