In a class of 50 students three fifths are girls. Each girl
brings a ribbon of length 2 3/4m and each boy brings 3 1/4m .
What is the total length of ribbon collected by the 50
students?
ANSWER
No of students in a class = 50
No of girls in the class = 3/5 of 50
=3/5 * 50
=150/50
=30
No of boys in the class = 50-30
=20
Length of the ribbons brought by girls = 2 3/4
=11/4
Length of the ribbon brought by boys = 3 1/4 =13/4
Total length of the Ribbon brought by girls and boys
=30* 11/4 + 20*13/4
=330/4 +260/4
=590/4
=147 1/4
Therefore , the total length of the ribbon is 161m

In an auditorium, 1/6 of the students are fifth graders, 1/3 are fourth graders, and 1/4 of the remaining students are third graders. If there are 96 students in the auditorium, how many second graders are there?
