The ratio of girls is 1/5th not the total people for suppose if there r 30 girls then no.of girls participated is 6 and if no.of boys r 24 then 1/8th is 3 nd total participated is 9 and ratio would be 9/54 which is 1/6 so data is inadequate.

List common dinominator(LCD) = 40
Convert the fraction to have a denominator
1/5 = 8/40,1/8 = 5/40
Add them, 8/40+5/40, take the common denominator.
8 + 5/40 = 13/40.

Say for Example total student is X. We have to assume as this number is not given;

Now, Boys participated = X/8,
Girls Participated = X/5,
Total Number of student participated = X/8 +X/5 = 13X/40,
Here if you dont know X you wil never be able to know value fo total number of student participated.
Thus data inadequate.

According to my opinion it should be 13/40, because

1/5+1/8 = 13/40,

because the question only ask about the What fraction of the total number of students took part in the fete?.

Ans is "Data inadequate".

Suppose ther are 18 students (10 girls, 8 boys).

1/5 of 10=2 (girls).

1/8 of 8=1 (boy).

Total participation=2+1=3.

Total students=10+8=18.

Answer = 3/18 = 1/6.

Answer cannot be determined until we have the "Ratio of girls to boys".

My option also 13/40. If we see the percentage based.

1/5& 1/8.
Lcm 40 and 8 + 5 = 13 then the answer is 13/40.
