You have a bag that contains 8 yellow marbles, 6 green marbles, and 5 red marbles.

What percent of the bag is red marbles?

Answer is 26.31%

The % of red marbles is 26.3157895

Answer: 26%

First you find the total number of the marbles by adding each colour together.

8+6+5=19 marbles

Then you divide the amount of red marbles by the total amount

5/19=0.263 ...

Then you multiply the decimal by 100 to get a percent.

0.263x100 = 26%
