To multiply mixed numbers you need to express the mixed
numbers as improper fractions.
y
=
3
1
X
2
4
8
5
The mixed numbers above have been expressed as improper
fractions below.
y
=
25
X
14

5
Next, you need to cross factor. Determine the
greatest common factor (GCF) for 25 and 5. The GCF for 25 and 5 is
5. Determine the greatest common factor (GCF) for 14 and 8.
The GCF for 14 and 8 is 2. Divide 25 and 5 by 5. Divide 14 and
8 by 2. Look below.
y
=

Multiply 5 times 7 to get 35. Multiply 4 times 1
to get 4. Y equals the fraction 35 over 4. Look
at the equation below.
