Answer 1

4 cups of sugar require 14 cups of sugar

Explanation:

Given

`(7)/(8)\ cup\ flour = (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 * (7)/(8)\ cup\ flour = (1)/(4)\ cup\ sugar * 4`

`(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 * (7)/(2)\ cup\ flour = 1\ cup\ sugar * 4`

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

`14\ cup\ flour = 4\ cup\ sugar`

Hence;4 cups of sugar require 14 cups of sugar
