Comparison Using Benchmark Fractions

The video tutorial explains how to use benchmark fractions like 1/2, 1/3, and 1/4 to compare other fractions. It demonstrates comparing fractions such as 3/5 and 2/7 using 1/2, and 9/13 and 5/12 using 1/3. The tutorial also covers equivalent fractions, showing how 3/12 and 5/20 are both equal to 1/4. The lesson concludes with a summary of the methods for comparing fractions using benchmarks.

What are benchmark fractions?

• Fractions that cannot be simplified

• Fractions that are equal to whole numbers

• Fractions that are always greater than 1

• Fractions used to compare other fractions

Which fraction is greater: 3/5 or 2/7?

• 3/5

• 2/7

• They are equal

• Cannot be determined

Why can't 1/2 be used as a benchmark for comparing 9/13 and 5/12?

• Both fractions are less than 1/2

• One fraction is equal to 1/2

• Both fractions are greater than 1/2

• 1/2 is not a benchmark fraction

Which fraction is closer to 1/3: 9/30 or 5/12?

• 9/30

• 5/12

• Neither is close

• Both are equally close

What is the equivalent fraction of 3/12?

• 1/5

• 1/2

• 1/3

• 1/4

How can 5/20 be simplified?

• 1/2

• 1/5

• 1/3

• 1/4

What conclusion can be drawn about 3/12 and 5/20?

• 5/20 is greater than 3/12

• They cannot be compared

• 3/12 is greater than 5/20

• They are equivalent
