Tammy had
45 as many mini cupcakes as Justin. Justin had
45 as many mini cupcakes as Will. If Will had 45 more mini cupcakes than Tammy, find the total number of mini cupcakes that was shared among these 3 children at first.
Tammy |
Justin |
Will |
4x4 |
5x4 |
|
|
4x5 |
5x5 |
16 u |
20 u |
25 u |
Justin is the repeated identity.
LCM of 5 and 4 = 20
Number of more mini cupcakes that Will had more than Tammy
= 25 u - 16 u
= 9 u
9 u = 45
1 u = 45 ÷ 9 = 5
Total number of mini cupcakes
= 16 u + 20 u + 25 u
= 61 u
= 61 x 5
= 305
Answer(s): 305
