Question

Gianni added 1 3/4 cup of pecans and 1 1/3 cup of walnuts to a recipe. How many cups of nuts did Gianni add to the recipe? I NEED AN ANSWER RIGHT AWAY!!!!
A. 2 4/7 cup

B. 2 1/12 cup

C. 3 1/12 cup

D. 3 1/3 cup

Answer 1

C - 3 1/12

Get a common denominator

3*3 / 4*3 + 1*4 / 3*4

Simplifies into 9/12 + 4/12

Adds to 13/12. 

12 goes into 13 1 time, leaving us with 1 1/12

Add the 1 to the 2 full cups that already existed in the original problem - 3 1/12
