A recipe calls for 1 3/4 cup of flour. How many cups would you need if you doubled the recipe? Simplify, and write your answer as a mixed number.
A) 2 2/8
B) 3 1/2
C) 2 3/4
D) 7/8
If the recipe calls for 1 3/4 cup of flour, then doubling the recipe would require 1 3/4 x 2 = 3 1/2 cup of flour.
Therefore, the answer is B) 3 1/2.
