Question

Pasha works as a food scientist. He designed a recipe for crackers that are 45% wheat flour by weight. He made a test batch of the crackers from 1 1/4 total pounds of ingredients. What weight of wheat flour did Pasha use in the test batch?

A. 9/16 pound
B. 4/5 pound
C. 9/25 pound
D. 11/16 pound

Answer 1

Pasha used 9/16 pound of wheat flour in the test batch.

Step-by-step explanation:

To find the weight of wheat flour Pasha used in the test batch, we can set up a proportion. Let x represent the weight of wheat flour. We know that 45% of the total weight of ingredients is wheat flour, so we can write the equation: 0.45 = x / 1.25. To solve for x, we can cross multiply and then divide by 1.25. The weight of wheat flour is approximately 0.5625 pounds, which is equivalent to 9/16 pound. Therefore, the answer is option A, 9/16 pound.
