The number of Jack's red staplers and Michael's brown staplers is the same.
The number of Jack's red staplers is repeated. The number of Michael's brown staplers is repeated. Make the number of Jack's red staplers and Michael's brown staplers the same. LCM of 1 and 4 is 2.
Number of brown staplers
= 6 u + 2 u
= 8 u
8 u = 64
1 u = 64 ÷ 8 = 8
Total number of staplers
= 6 u + 2 u + 2 u + 1 u
= 11 u
= 11 x 8
= 88
Answer(s): 88
