Question

A jar has 32 marbles. Some are blue and the rest are green. There are three times as many green marbles as blue. How many green marbles are in the​ jar

Answer 1

Answer: 24

Explanation:

Number of marbles in jar = 32

Let blue marbles be represented by b.

Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b

We then add them together. This will be:

3b + b = 32

4b = 32

b = 32/4

b = 8

There are 8 blue marbles

Since green is 3× blue. Therefore,

Green = 8 × 3 = 24 marbles
