Question

Samuel has a collection of toy cars. His favorites are the 27 red ones which make up 60%, percent of his collection.

Answer 1

I'm just gonna assume that the question is what's the total number of cars he has/ the other part of his collection

His whole collection has 45 cars in it. I got that by multiplying 60% by 27 

the other 40% of his collection is made up of 18 cars
