89The number of girls in Class 5N and Class 5P is the same. Make the numerators the same.
2x43x4 of students in Class 5N =
89 of students in Class 5P
812 of students in Class 5N =
89 of students in Class 5P
Total number of boys
= 4 u + 1 u
= 5 u
5 u = 20
1 u = 20 ÷ 5 = 4
Number of students in Class 5P
= 9 u
= 9 x 4
= 36
Answer(s): 36
