3. Yes, 3.75 is correct for the area of the parallelogram.

For the sum of fractions, you have done the first step correctly.

The next step is to find the LCM of the three denominators. Confirm that it is 24. Now convert each fraction to an equivalent having 24 as denominator. Then add the numerators. The answer should be 199/24 or 8 7/24.

add 1 3/8+ 4 3/4+ 2 1/6

First you need to find the common denominator and convert the fractions to their equivalents.

1 3/8 = 1 9/24
4 3/4 = 4 18/24
2 1/6 = 2 4/24
