Question

a recipe that makes 12 muffins calls for 2 1/2 cups of flour. how much flour is needed to make 18 muffins

Answer 1

Answer:  $3\frac{3}{4}$ cups of flour

=============================

Work Shown:

A = 12 muffins

B = 2.5 cups of flour

C = 18 muffins

D = x cups of flour

A/B = C/D

12/2.5 = 18/x

12x = 2.5*18

12x = 45

x = 45/12

x = 3.75

x = $3\frac{3}{4}$
