Question

Jerome is making beef stew for his family. The recipe calls for 3.5 pounds (lbs.) of stew meat. He notices that he has 1.25 pounds (lbs.) in his refrigerator. How much stew meat should buy when he goes to the grocery in order to have enough? a) What operation (add, subtract, multiply or divide) would you use to solve this? b) How did you know?

Answer 1

EXPLANATION

Let's see the facts:

Call for---> 3.5 lbs of stew meat

Refrigerator -------> 1.25 lbs stew meat

He would buy:

Required - Available ----> 3.5 - 1.25 = 2.25 lbs of stew meat

The operation that we apply is subtraction because 3.5lbs (required) is greater than 1.25lbs (available).
