Know the Answer?

Ruth Mcneil · Answer 1

You first divide the number by 100 and then multiply it by the percentage that you are given

Raphael · Answer 2

i learned it as "is" over "of" "per" over "cent"

cent means 100

what IS 30% OF 670

so that would be

x/670 30/100

and then you cross multiply

100x = 20100

x = 201
