Question

what is 1 +1 1/2 +1 1/2 + 1 3/4 + 1 3/4+ 1 3/4+ 1 3/4 +2

Answer 1

You may either convert all of the mixed numbers to improper fractions, then back to a mixed number

or

you may add all of the whole numbers, then add all of the fractions (using a common denominator).

Let's do method (1):

1 +1 1/2 +1 1/2 + 1 3/4 + 1 3/4+ 1 3/4+ 1 3/4 +2

1 + 3/2 + 3/2 + 7/4 + 7/4 + 7/4 + 7/4 + 2 [the LCD is 4]

4/4 + 6/4 + 6/4 + 7/4 + 7/4 + 7/4 + 7/4 + 8/4

(4 + 6 + 6 + 7 + 7 + 7 + 7 + 8)/4

52/4
