Question

these televisions are similar. find w. 54 36 12

Explanation:

Step1: Set up the proportion

Since the televisions are similar, the ratios of their corresponding sides are equal. So, \(\frac{w}{54}=\frac{12}{36}\).

Step2: Solve the proportion for \(w\)

Cross - multiply: \(36w = 54\times12\). Then \(36w=648\). Divide both sides by 36: \(w=\frac{648}{36}\).

Answer:

\(18\)
