Answer:

4 cups of sugar require 14 cups of sugar

Step-by-step explanation:

Given

$\frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar$

Required

Determine the cups of flour for 4 cups of sugar

First, we need to determine the unit rate for 1 cup of sugar.

This is done by multiplying both sides by 4

$4 * \frac{7}{8}\ cup\ flour = \frac{1}{4}\ cup\ sugar * 4$

$\frac{7}{2}\ cup\ flour = 1\ cup\ sugar$

Next, we determine cup of flour for 4 cups of sugar.

This is done by multiplying both sides by 4

$4 * \frac{7}{2}\ cup\ flour = 1\ cup\ sugar * 4$

$2 * 7\ cup\ flour = 4\ cup\ sugar$

$14\ cup\ flour = 4\ cup\ sugar$

<em>Hence;4 cups of sugar require 14 cups of sugar</em>
