A package of colored paper contains 20 pieces of yellow paper. This represents 25% of the total pieces of colored paper in the package. Write 25% as a rate per 100 and How many total pieces of colored paper are in the package?
percent means parts out of 100 25%=25/100=5/20=1/4
so 20=1/4 of all paper 'of' mean smultiply 20=1/4 times all paper multiply both sides by 4/1 to clear fraction since 4/1 times 1/4=4/4=1 80/1=4/4 times all paper 80= all paper
