To compare two values, first convert the values to the same form.

Then, compare the values using an inequality sign: < : __________ > : ____________

• less than; greater than

• greater than; less than

• equal to; not equal to

• not equal to; equal to

Practice converting between the three forms of numbers by completing the table below: FRACTION: 1/3, 2/3, 2/5, 1.5 DECIMAL: 0.2, 0.75, ______, ______ PERCENT: 50%, ______, 12.5%, ______ Fill in the missing decimal and percent values.

• DECIMAL: 1/3 = 0.333..., 2/3 = 0.666..., 2/5 = 0.4, 1.5 = 1.5 PERCENT: 1/3 = 33.3%, 2/3 = 66.7%, 2/5 = 40%, 1.5 = 150%

• DECIMAL: 1/3 = 0.25, 2/3 = 0.5, 2/5 = 0.2, 1.5 = 1.0 PERCENT: 1/3 = 25%, 2/3 = 50%, 2/5 = 20%, 1.5 = 100%

• DECIMAL: 1/3 = 0.5, 2/3 = 0.75, 2/5 = 0.6, 1.5 = 1.2 PERCENT: 1/3 = 50%, 2/3 = 75%, 2/5 = 60%, 1.5 = 120%

• DECIMAL: 1/3 = 0.1, 2/3 = 0.2, 2/5 = 0.3, 1.5 = 0.4 PERCENT: 1/3 = 10%, 2/3 = 20%, 2/5 = 30%, 1.5 = 40%
