1. The problem is to find 7% of a number or value. 2. The formula to calculate a percentage of a number is: $$\text{Percentage value} = \frac{\text{Percentage}}{100} \times \text{Total value}$$ 3. Here, the percentage is 7%, so we write it as $\frac{7}{100}$. 4. To find 7% of any number $x$, multiply $x$ by $\frac{7}{100}$: $$7\% \text{ of } x = \frac{7}{100} \times x$$ 5. For example, if $x=50$, then: $$7\% \text{ of } 50 = \frac{7}{100} \times 50 = \frac{7 \times 50}{100} = \frac{350}{100} = 3.5$$ 6. So, 7% of 50 is 3.5. This method works for any value you want to find 7% of by substituting $x$ with that value.
