what is 28% of 75

OpenStudy (stamp):

\[\%=\frac{}{100}\]\[28\%(75)=\frac{28}{100}(75)\]

OpenStudy (anonymous):

well 10% of 75 is 7.5 therefore 20% is 15 5% is half of 10, which is 3.75 1% is .75, thus 3% is 2.25 15 + 3.75 + 2.25 = 28% of 75

Twenty-two is what percent of 55?

OpenStudy (amistre64):

its 28 of the 1% of 75 :)

OpenStudy (stamp):

Or \[\frac{28}{100}(75)=28\frac{3}{4}=3(7)=21\]

OpenStudy (amistre64):

if n is a percentage of m then n*100/m is the percentage
