watch the following video and then answer the question(s) below.

Explanation:

Step1: Define the proportion

Let \( x \) be 80% of 150. We set up the proportion \(\frac{x}{150}=\frac{80}{100}\) (since 80% is \(\frac{80}{100}\) and we want to find what part \( x \) is of 150).

Step2: Solve for \( x \)

Cross - multiply: \( 100x = 80\times150 \). Calculate \( 80\times150 = 12000 \). Then \( x=\frac{12000}{100}=120 \).

Answer:

A. 120
