Answer:

27 girls

18 boys

Explanation:

Convert 60% to a decimal.

  • 60% · .01 = 0.6

Multiply 45 students by 0.6 to find the number of girls in the class.

  • 45 * 0.6 = 27 girls

Subtract this amount from the total number of students in the class.

  • 45 - 27 = 18 boys

There are 27 girls and 18 boys in the class.
