The number of girls who came in white shirts is repeated. Make the number of girls who came in white shirts the same. LCM of 1 and 2 is 2.
Total number of pupils
= 5 u + 1 u + 4 u + 2 u
= 12 u
12 u = 444
1 u = 444 ÷ 12 = 37
Number of pupils in gold shirts
= 5 u + 4 u
= 9 u
= 9 x 37
= 333
Answer(s): 333
