Answer:
25 percent
Step-by-step explanation:
Let the number of girls be x. Then the number of boys is 3*x = 3x.
the total number of students , i.e. 100 percent the number of students is therefore x + 3x = 4x.

x = 100/4 percent
= 25 percent
therefore, the percentage of girls is 25

A loss of 4 points would be -4
Just add the fractions like 1/4 hours is 15 minutes, 1 3/8 is 11/8 that is 1 hour and 12,5 minutes then 1/2 hours is 30 minutes adding all together gives 1 hour and 57,5 minutes
