TEKS Objective 111.17. Mathematics, Grade 5.
(2) Number, operation, and quantitative
reasoning. The student uses fractions in
problem-solving situations. The student is
expected to (B) compare two fractional
quantities in problem-solving situations
using a variety of methods, including common
denominators.
4
In comparing fractions If the denominators
are the same, the fraction with the largest
numerator is larger.
5
Like Denominators Example 6 is
greater than 3 , or 7
7 6 gt 3 7 7
6
In comparing fractions If the denominators
are different, first change the denominators
to the lowest common denominator. Once
this is complete, the fraction with the
largest numerator is larger.
7
Unlike Denominators Example 6 is less
than 5 8 4
First change the fractions to the
lowest common denominator. 6 is
less than 10 , therefor 8
8 6 lt 5 . 8

In comparing fractions Equivalent
Fractions can occur when denominators differ
prior to finding the lowest common
denominator, but are the same after
determining the lowest common denominator.
9
Equivalent Fractions
Example 3 is equal to
6 4 8
First change the fractions to
the lowest common denominator. 6
is equal to 6 , therefor 8
