89The number of boys in Class 5T and Class 5U is the same. Make the numerators the same.
2x43x4 of students in Class 5T =
89 of students in Class 5U
812 of students in Class 5T =
89 of students in Class 5U
Total number of girls
= 4 u + 1 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of students in Class 5U
= 9 u
= 9 x 3
= 27
Answer(s): 27
