The number of Gabriel's white staplers and Lee's gold staplers is the same.
The number of Gabriel's white staplers is repeated. The number of Lee's gold staplers is repeated. Make the number of Gabriel's white staplers and Lee's gold staplers the same. LCM of 2 and 3 is 2.
Number of gold staplers
= 1 u + 2 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Total number of staplers
= 1 u + 2 u + 2 u + 10 u
= 15 u
= 15 x 9
= 135
Answer(s): 135
