67The number of boys in Class 5V and Class 5W is the same. Make the numerators the same.
3x24x2 of students in Class 5V =
67 of students in Class 5W
68 of students in Class 5V =
67 of students in Class 5W
Total number of girls
= 2 u + 1 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Number of students in Class 5W
= 7 u
= 7 x 6
= 42
Answer(s): 42
