Question

3 scale up or scale down to determine each unknown quantity. f) \\(\frac{1200 \text{ boxes}}{9 \text{ truckloads}} = \frac{?}{3 \text{ truckloads}}\\)

Explanation:

Step1: Analyze the ratio

We have a proportion \(\frac{1200}{9}=\frac{x}{3}\) (let \(x\) be the unknown number of boxes).

Step2: Solve for \(x\)

Cross - multiply: \(9x = 1200\times3\)
\(9x=3600\)
Divide both sides by 9: \(x=\frac{3600}{9}\)
\(x = 400\)

Answer:

400 boxes
