Answer 1

Answer:

please mark me as brainilists

Step-by-step explanation:

2/5 are boys then 3/5 are girls

These added together equal 5/5 which is the total number in the class ( 45 in this example )

45 divided by 5 equals 9

3 fifths would be 3 x 9 = 27 girls

The other way is to let x = number of girls

multiply 45 ( total # students) by (3/5)

x = 45 (3/5)

x = 135/5 = 27 girls
