Mrs Tim baked
15 as many blueberry cupcakes as chocolate chip cupcakes. She also baked
23 as many blueberry cupcakes as cheese cupcakes. If she baked a total of 120 cupcakes, how many blueberry cupcakes did she bake?
Blueberry |
Chocolate Chip |
Cheese |
1x2 |
5x2 |
|
2x1 |
|
3x1 |
2 u |
10 u |
3 u |
The number of blueberry cupcakes is the repeated identity. Make the number of blueberry cupcakes the same. LCM of 1 and 2 is 2.
Total number of cupcakes
= 2 u + 10 u + 3 u
= 15 u
15 u = 120
1 u = 120 ÷ 15 = 8
Number of blueberry cupcakes
= 2 u
= 2 x 8
= 16
Answer(s): 16
