Answer 1

To solve the proportion \( \frac{15}{2} = \frac{y}{75} \), you can use cross-multiplication. Here's how it's done:

1. Cross-multiply: \[ 15 \cdot 75 = 2 \cdot y \]

2. Calculate \( 15 \cdot 75 \): \[ 15 \cdot 75 = 1125 \]

3. Now your equation is: \[ 1125 = 2y \]

4. To isolate \( y \), divide both sides by 2: \[ y = \frac{1125}{2} = 562.5 \]

So, the solution is: \[ y = 562.5 \]
