for exercises 1-6, solve each problem.

1. kendall is making bread. her recipe calls for 3 cups of flour and \\(\frac{3}{4}\\) cup of sugar. if she increases the flour to 4 cups, how much sugar will she need?

Explanation:

Step1: Set up proportion

Let \( x \) be the new amount of sugar. The ratio of flour to sugar should remain constant. So, \(\frac{3}{\frac{3}{4}}=\frac{4}{x}\)

Step2: Solve the proportion

First, simplify \(\frac{3}{\frac{3}{4}}\). Dividing by a fraction is multiplying by its reciprocal, so \( 3\times\frac{4}{3} = 4 \). Now our equation is \( 4=\frac{4}{x} \). Cross - multiply: \( 4x = 4 \). Divide both sides by 4: \( x = 1 \)

Answer:

1 cup
