9

using common denominators. His work is shown below.

What errors did Sadi make? Check all that apply.

The common denominator is 6, not 9.

He should have multiplied 2/3 by 3/3, not 1/3 .

He should have gotten a common numerator, not a common denominator.

The fraction 2/3 is greater than 5/9, not less

than 5/9.
