Question

In a jar, 25% of the marbles are red. If there are 45 red marbles in the jar, how many marbles are in the jar altogether?

​

Answer 1

Answer: 180 marbles

Explanation:

25 percent can be converted to 1/4 and 4 x 1/4 = 1 and/or whole

Now since 45 marbles = 25 percent/1 /4 of WHAT is in the jar now we can multiple 45 x 4 (times 4 to make the 1/4 into a whole) which gives up 180 marbles total.

Hopefully I explained it in a way you can understand

Hope this helped
