Aug 17 Question:
Nick is making bread dough.
- The recipe requires 3⁄4 cup of flour and 11⁄8 teaspoons of salt.
- Nick wants to make the recipe using 1 cup of flour.
To maintain the ratio, how much salt is required when 1 cup of flour is used?
11⁄2 teaspoons of salt are required.
Let x be the amount of salt required. Since the ratio of salt to flour remains the same,
11⁄8 : 3⁄4 = x : 1
(3⁄4)x = 11⁄8
x = (4⁄3)(11⁄8) = (4⁄3)(9⁄8) = 3⁄2
