Question

question 2
a recipe calls for 5 cups of flour for every 3 teaspoons of salt. if you wanted to make a larger batch of the same recipe with 15 cups of flour, how much salt would you need?

Explanation:

Step 1: Set up proportion

Let \( x \) be the salt needed. The ratio of flour to salt is constant, so \( \frac{5}{3}=\frac{15}{x} \).

Step 2: Cross - multiply

Cross - multiplying gives \( 5x = 15\times3 \).

Step 3: Solve for x

Simplify the right - hand side: \( 5x=45 \). Then divide both sides by 5: \( x = \frac{45}{5}=9 \).

Answer:

9 teaspoons
