i have 3 1/8 pounds of macaroni and want to make 10 equal serving of macaroni salad. how many pounds of macaroni do i have for each serving

Answer 1

make 3 1/8 into an improper fraction by multiplying 8X3 + 1 over 8= 25/8            now divide 10 into 25/8 because you want 10 equal servings.   When you do this you get .3125 pounds   

Answer 2

you have 25/8 ÷10 equal servings
= 5/16 or 0.3125 servings
