Question

A bag contains 78 marbles, some green and some blue. The ratio of green marbles to

blue ones is 2: 4. How many green marbles are there?

Answer 1

Answer:


X= 15 marbles

Answer 2

15.

Explanation:

Let's call the number of green marbles "x". Then the number of blue marbles is 4x.

The total number of marbles is x + 4x = 5x = 78

So, x = 78/5 = 15.6

There are x = 15 green marbles in the bag.
