Mrs Archie baked
12 as many chocolate chip cupcakes as blueberry cupcakes. She also baked
25 as many chocolate chip cupcakes as cherry cupcakes. If she baked a total of 88 cupcakes, how many chocolate chip cupcakes did she bake?
Chocolate Chip |
Blueberry |
Cherry |
1x2 |
2x2 |
|
2x1 |
|
5x1 |
2 u |
4 u |
5 u |
The number of chocolate chip cupcakes is the repeated identity. Make the number of chocolate chip cupcakes the same. LCM of 1 and 2 is 2.
Total number of cupcakes
= 2 u + 4 u + 5 u
= 11 u
11 u = 88
1 u = 88 ÷ 11 = 8
Number of chocolate chip cupcakes
= 2 u
= 2 x 8
= 16
Answer(s): 16
