Re: Algebra

1742 are not circular

If 74% are circular, then 26% are not circular.

Find 1742 is 26% of what number.

a = pb is the percent equation.
a = = the "part", p = "percent", and b = the "whole"

a = pb
1742 = 0.26b   {substituted 1742 in for the part and 0.26 in for the percent (as a decimal)}
b = 6700   {divided each side by 0.26}

there are 6700 signs total
