Erika had
67 as many mini cupcakes as Tommy. Tommy had
35 as many mini cupcakes as Bryan. If Bryan had 119 more mini cupcakes than Erika, find the total number of mini cupcakes that was shared among these 3 children at first.
Erika |
Tommy |
Bryan |
6x3 |
7x3 |
|
|
3x7 |
5x7 |
18 u |
21 u |
35 u |
Tommy is the repeated identity.
LCM of 7 and 3 = 21
Number of more mini cupcakes that Bryan had more than Erika
= 35 u - 18 u
= 17 u
17 u = 119
1 u = 119 ÷ 17 = 7
Total number of mini cupcakes
= 18 u + 21 u + 35 u
= 74 u
= 74 x 7
= 518
Answer(s): 518
