Question

There are white, blue, and red boats in a marina. Five-sixths of the boats in the marina are white, 2/5 of the remaining boats are blue, and the rest are red. If there are 12 red boats, how many boats are in the marina?

Answer 1

first find out what 5/6 of 12 is and then add the sum to 12 then you would do the same thing except with 2/5 and add it to the sum you had before.
