15% of the kids at CMS are late every day. If there are 900 kids at CMS how many are NOT late every day?

765 kids

Step-by-step explanation:

There are two ways to solve this.

Either you can solve by finding the 15% that are late and subtracting that from 900, or you can find the 85% of kids that are not late.

Method One:

15%=0.15

900 x 0.15 = 135

900-135= 765

Method 2:

100-15=85%

85%=0.85

900 x 0.85=765

Either way, you get 765.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
