Mrs Simon baked
12 as many cranberry cupcakes as cheese cupcakes. She also baked
27 as many cranberry cupcakes as banana cupcakes. If she baked a total of 104 cupcakes, how many cranberry cupcakes did she bake?
Cranberry |
Cheese |
Banana |
1x2 |
2x2 |
|
2x1 |
|
7x1 |
2 u |
4 u |
7 u |
The number of cranberry cupcakes is the repeated identity. Make the number of cranberry cupcakes the same. LCM of 1 and 2 is 2.
Total number of cupcakes
= 2 u + 4 u + 7 u
= 13 u
13 u = 104
1 u = 104 ÷ 13 = 8
Number of cranberry cupcakes
= 2 u
= 2 x 8
= 16
Answer(s): 16
