How are youSadi wanted to compare the fractions 3

and 5

9

using common denominators. His work is shown below.

The common denominator is 9. Two-thirds times one-third = two-ninths. Two-ninths less-than five-ninths. So, two-thirds is less-than five-ninths.

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.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
