1. **State the problem:** We need to find what percent of students take the bus to school given the total votes and the number of votes for the bus. 2. **Formula:** The percentage is calculated by $ \text{Percent} = \frac{\text{Part}}{\text{Total}} \times 100 $. 3. **Apply the formula:** Here, the part is the number of students who take the bus, which is 90, and the total number of students is 150. 4. **Calculate:** $$\text{Percent} = \frac{90}{150} \times 100$$ 5. **Simplify the fraction:** $$\frac{90}{150} = \frac{\cancel{90}}{\cancel{150}} = \frac{3}{5}$$ 6. **Multiply by 100:** $$\frac{3}{5} \times 100 = 3 \times 20 = 60$$ 7. **Answer:** Approximately 60% of students take the bus to school.
