Find the range of the following data set. 1 1/4,5/8,3/4,1/2,1 1/2, 1 3/4

A. 1

B. 1 1/8

C. 1 1/4

1 1/4 = 1 2/8

5/8 = 5/8

3/4 = 6/8

1/2 = 4/8

1 1/2 = 1 4/8

1 3/4 = 1 6/8

So, the biggest number (1 6/8) - the smallest number (4/8) = 10/8

But to subtract fractions, you must do a little rule

1x8=8+6=14/8 - 4/8 which is 10/8 or 1 1/4

The answer is C
