Question

3 upon 5 total number of students in a school are girls.
(a) What fraction of the students are boys?
(b) If there are 164 boys, how many are girls?​

Answer 1

Answer:

ans a ) if 3/5 are girls , then total no of students + 5/5 ,

                        total no of boys = 5/5 - 3/5 = 2/5

ans b) now 2/5 = 164 , then 1/5 = 164/2 = 82

therefore 1/5 +2/5 = 82 +164 = 246 girls
