67The number of boys in Class 2V and Class 2W is the same. Make the numerators the same.
3x24x2 of students in Class 2V =
67 of students in Class 2W
68 of students in Class 2V =
67 of students in Class 2W
Total number of girls
= 2 u + 1 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of students in Class 2W
= 7 u
= 7 x 4
= 28
