A jar contains 125 marbles. Given 9% of the marbles are green, 11% of the marbles are blue, and the rest are red, how many red marbles are in the jar?

It shoul be 80% is red :>

Step-by-step explanation:

100

Step-by-step explanation:

Since we already know 9% is green and 11% is blue, 20% (9+11) are NOT red.

Now that that we know 80%(100-20) are red, we need to find 80% OF 125 total marbles.

Since the word "of" indicates multiplication, we multiply 125×0.80, which equals 100
