1. The problem is to convert $\frac{15}{150} \times 100$ to a percentage. 2. Start by simplifying the fraction $\frac{15}{150}$: $$\frac{15}{150} = \frac{15 \div 15}{150 \div 15} = \frac{1}{10}.$$ 3. Next, multiply the simplified fraction by 100: $$\frac{1}{10} \times 100 = \frac{100}{10} = 10.$$ 4. Therefore, $\frac{15}{150} \times 100$ equals $10$%, which means the result is 10 percent.
