Step-by-step explanation:
If 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
