Benchmarking Fractions

by Aaron Bierie

​So if 2/3 is greater than 1/2 and 4/10 is less than 1/2 That means that 2/3 is greater than 4/10.

​Cross Multiply

• ​Multiply the top of the first fraction by the bottom of the second fraction

• ​Write that answer on the left

• ​Multiply the bottom of the first fraction by the top of the 2nd fraction

• ​Write that number on the right.

• ​Compare the numbers to decide which one is greater.

​2x10=20 3x4=12

​20 is greater than (>) 12 so 2/3 is greater than 4/10.
