key idea

A benchmark is a reference number that can be used to compare two fractions.

If one fraction is less than the benchmark and a second fraction is greater, the first fraction is less than the second.

solution

First, compare each fraction to the benchmark.

Compare

3

2

to the benchmark, 1.

These fraction bars show

3

2

and 1. Compare the shaded areas.

3

2

1

The shaded area is greater for

3

2

.

So,

3

2

is greater than 1.

Compare

1

5

to the benchmark, 1.

These fraction bars show

1

5

and 1. Compare the shaded areas.

The shaded area is less for

So,

1

is less than 1.

Now, use this information to compare the two fractions.
