Answer 2

Answer:

27 girls

18 boys

Step-by-step 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.
