67The number of girls in Class 1V and Class 1W is the same. Make the numerators the same.
2x33x3 of students in Class 1V =
67 of students in Class 1W
69 of students in Class 1V =
67 of students in Class 1W
Total number of boys
= 3 u + 1 u
= 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Number of students in Class 1W
= 7 u
= 7 x 4
= 28
Answer(s): 28
