Convert the mixed number to an improper fraction. 3 1/4 a. 7/4 b.13/4 c. 31/4 d. 35/4

To change 3 1/4 to an improper fraction, we must transfer the mixed number, which contains a fraction (1/4) and whole number (3), to just a fraction.

To do this, we must transfer 3 to a fraction with the denominator being 4

We can do 3 x 4 to find the number on top.
3 x 4 = 12

To check to make sure we did it right, we can do 12 / 4 which = 3 (√ check!)

Then we add 1/4 to 12/4 to get B. 13/4
