This module is from Fundamentals of Mathematics by Denny Burzynski and Wade Ellis, Jr. This module discusses how to add and subtract mixed numbers. By the end of the module students should be able to add and subtract mixed numbers.
Section overview
The Method of Converting to Improper Fractions
To add or subtract mixed numbers, convert each mixed number to an improper fraction, then add or subtract the resulting improper fractions.
Sample set a
Find the following sums and differences.
. Convert each mixed number to an improper fraction.
Now add the improper fractions
.
The LCD = 20.
Thus,
.
. Convert the mixed number to an improper fraction.
The LCD = 24.
Thus,
.
Practice set a
Find the following sums and differences.
