larger. Explain your reasoning using the
common denominator strategy
.

Using common denominator strategy
⅗
is bigger than
⅖
because looking at the numerators 3 is
bigger than 2.
2.

larger. Explain your reasoning using the
common numerator strategy

⅗
is bigger than
⅜
because comparing numerations when they have a common denominator
(40)
⅗
is 24/40 and
⅜
is 15/40 and 24 is bigger than 15
3.
Use the benchmark strategy to determine which of the following two fractions is larger.
