Question

Of the 800 participants in a marathon 220 are running to raise money for a cause. How many participants out of 100 are running for a cause?

Answer 1

27.5 /100 are running for a cause

Explanation:

We know that 220/800 are running for a cause

Divide the top and bottom by 8 to get the fraction out of 100

220 /8 =27.5

800/8 = 100

27.5 /100 are running for a cause
