The number of boys who came in yellow windbreakers is repeated. Make the number of boys who came in yellow windbreakers the same. LCM of 1 and 3 is 3.
Total number of students
= 4 u + 1 u + 6 u + 3 u
= 14 u
14 u = 434
1 u = 434 ÷ 14 = 31
Number of students in white windbreakers
= 4 u + 6 u
= 10 u
= 10 x 31
= 310
Answer(s): 310
