Question

if 25% of cheerleaders are surveyed and 170 of them say their favorite color red,what is most reasonable prediction of the number of cheerleaders who would pick red as their favorite red?

Answer 1

680

Explanation:

In this problem, we do not need to know how much cheerleaders were surveyed. All we need to know is that they surveyed 25% and 170 said red was there favorite color.

100% would be the full amount.

25% is 1/4 of 100%.

170 is 1/4 of x.

so we would do 170*4 to get to 100% and get x which would be 680.

So x=680.

In other words, 170 is just a part of the whole, it is 1/4 of the whole. If we had 4/4, that would be 1/4*4. So we can just do 1/4 which is 170*4.

I hope this helped.

Answer 2

680

Explanation:

680 because 25% is one-fourth of 100% so i multiplied 170 by 4 and i got 680
