Question

1. 12.6 is what percent of 42?

Explanation:

Step1: Set up the percentage formula

Let \( x\) be the percentage. The formula for percentage is \(\text{Part}=\frac{x}{100}\times\text{Whole}\). Here, the part is \(12.6\) and the whole is \(42\). So, \(12.6=\frac{x}{100}\times42\).

Step2: Solve for \(x\)

First, rewrite the equation as \(x=\frac{12.6\times100}{42}\).
Calculate \(12.6\times100 = 1260\). Then, \(\frac{1260}{42}=30\).

Answer:

\(30\)
