• In percent problems, just as in
fraction problems, “of” implies
multiplication: “x percent of a
number means “x% times a
number.”
Different Ways for
Percents
Percent to Decimal-divide the percent by
100 (83 divided by 100 = 0.83).
• Percent to Fraction- Place the number in
the percent over 100 and reduce.
Example of a Problem
• For example, “48% of the
students in the school are boys”
means that out of every 100
students in the school, 48 are
boys.
