The number of Ryan's pink files and Bobby's yellow files is the same.
The number of Ryan's pink files is repeated. The number of Bobby's yellow files is repeated. Make the number of Ryan's pink files and Bobby's yellow files the same. LCM of 2 and 3 is 2.
Number of yellow files
= 1 u + 2 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Total number of files
= 1 u + 2 u + 2 u + 6 u
= 11 u
= 11 x 8
= 88
Answer(s): 88
