Elyse had
57 as many mini cupcakes as Jeremy. Jeremy had
34 as many mini cupcakes as Luke. If Luke had 26 more mini cupcakes than Elyse, find the total number of mini cupcakes that was shared among these 3 children at first.
Elyse |
Jeremy |
Luke |
5x3 |
7x3 |
|
|
3x7 |
4x7 |
15 u |
21 u |
28 u |
Jeremy is the repeated identity.
LCM of 7 and 3 = 21
Number of more mini cupcakes that Luke had more than Elyse
= 28 u - 15 u
= 13 u
13 u = 26
1 u = 26 ÷ 13 = 2
Total number of mini cupcakes
= 15 u + 21 u + 28 u
= 64 u
= 64 x 2
= 128
Answer(s): 128
