How many servings are in 12 cups of rice a.
Alex777 [14]
     One serving is 3/4 cups of rice. To find out how many serving there are in 12 cups of rice, you divide 12 by 3/4. (When dividing fractions, don't ask why. Flip the second one over and multiply).
   12/(3/4) = 12 *(4/3) = 48/3 = 16
     There are 16 servings of rices in 12 cups.
