1/5*60=60/5=12 people invited

boys : 1/3*12=12/3=4 boys
girls: 12-4=8 girls
1 5 1

Ankita invited1/5 of her classmate in a party:-
 
i.e total classmates are:- \frac{1}{5} * 60   [bcos total students in class are 60]
i.e total class mates are:12.

1/3 invited classmates are boys=>  12* \frac{1}{3} = 4 boys.

if there are 12 students then girls are:12-4=8

hence there are total 8 girls are invited in the party.
