CONVERTING BETWEEN FORMS

To compare fractions, decimals, and percentages, convert them to the same form. Fraction > percentage: divide then × 100. Decimal > percentage: × 100. For example, to compare 3/5 and 0.7: 3/5 = 60% and 0.7 = 70%, so 0.7 is bigger.

Convert 3/5 to a percentage

13/5 = 3 ÷ 5 = 0.6

20.6 × 100 = 60%

= 60

Which is larger: 70% or 3/4?

13/4 = 75%

275% > 70%

33/4 is larger

= 3/4

LEADER TIP

When comparing fractions with different denominators, convert to percentages. It's a universal comparison tool.
