Todays Learning Target:

Add and subtract mixed numbers with unlike denominators.

Ex:

1 6/24

+3 7/8

 

First find the LCD (Least Common Denominator a.k.a. Liquid Crstal Display. Hahaha Very funny Mr.Tubbs)

default

In this case, the LCD would be 24. Next, you will need to find equivalent denominators. After that, multiply the denominator (demominator) and the numerator of the fraction to what ever number it takes to get to the LCD. In this case, 8 would be 7x3 and 8x3 which should get you 21/24. The top fraction should be 6x1 and 24x1. Then, you add or subtract the fractions and then add or subtract the whole numbers.

Doing all this should get you something that looks a little like this:

1 6/24 x1/1=6/24

3 7/8 x 3/3=21/24

=5 3/24.

If you did not bother to read my explanation, read the summary below:

1.) Find the LCD

2.) Find equvalent fractions

3.) Add or subtract the fractions

4.) Add or subtract the whole numbers
