Adding Fractions With Unlike Denominators - Word Problems
Practice Preview
Bob is in charge of doing the laundry at his house. This Monday he did
4
13
of a load of laundry and on Tuesday he did another
1
15
of a load of laundry. How many loads of laundry he did in the first two days of the week?
(Solve and reduce the fraction.)
Explanation
Remember, we cannot add fractions until the denominators are same. So, we have to find the least common denominator.
Least Common Denominator (LCD) of 13 and 15 is 195.
Now, we have to make sure both fractions have the same new denominator 195.
You can write fraction
4
13
as
4x15
13x15
=
60
195
You can write fraction
1
15
as
1x13
15x13
=
13
195
Now, both fractions have same denominator and we are ready to add
60
195
+
13
195
=
60+13
195
=
73
195
