Question

60% of the 7th and 8th graders attended the school dance. If 150 students are in the 7th and 8th grades, how many students went to the dance?

Answer 1

To find the number of 7th and 8th graders who went to the dance, calculate 60% of 150 students, resulting in 90 students attending the dance.

Step-by-step explanation:

The question asks how many students attended the school dance if 60% of the 7th and 8th graders went, given that there are 150 students in total in those grades. To calculate this, we use the formula for percentage:

1. Calculate the total number of students who went to the dance by finding 60% of 150.
2. Convert the percentage to a decimal by dividing 60 by 100, which is 0.6.
3. Multiply 0.6 by 150 to find the number of students. 0.6 × 150 = 90 students.

Therefore, 90 students from the 7th and 8th grades attended the school dance.
