Natalie had
47 as many mini cupcakes as Ahmad. Ahmad had
35 as many mini cupcakes as Dylan. If Dylan had 161 more mini cupcakes than Natalie, find the total number of mini cupcakes that was shared among these 3 children at first.
Natalie |
Ahmad |
Dylan |
4x3 |
7x3 |
|
|
3x7 |
5x7 |
12 u |
21 u |
35 u |
Ahmad is the repeated identity.
LCM of 7 and 3 = 21
Number of more mini cupcakes that Dylan had more than Natalie
= 35 u - 12 u
= 23 u
23 u = 161
1 u = 161 ÷ 23 = 7
Total number of mini cupcakes
= 12 u + 21 u + 35 u
= 68 u
= 68 x 7
= 476
Answer(s): 476
