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