There is 48 students in a class. 7 out of 8 are females what percent are females?

2 answers

(7/8)48 = 7*6 = 42 are female

100 (42/48) = 87.5 %
Looking at your other question I wonder if you typed this one incorrectly as well.
Could you perhaps have meant that there were 7 females for 8 males?
That would be more common.
In that case 7/15 are female
100(7/15) = 46.7 %
