Question

Last month Kim trained 3 times as many dogs as cats. If the total number of cats and dogs she trained last month is 28, how many cats did Kim train?

Answer 1

if there are 3 times as many dogs as there are cats, then that means there are 4 "parts" total.

3 × n dogs + 1 × n cats = 4 × n animals = 28

We know that the dogs account for 3/4 of the animals, while the cats account for the remaining quarter.

Hope I helped:P
