Mrs George baked
12 as many cranberry macarons as vanilla macarons. She also baked
23 as many cranberry macarons as apple macarons. If she baked a total of 72 macarons, how many cranberry macarons did she bake?
| Cranberry |
Vanilla |
Apple |
| 1x2 |
2x2 |
|
| 2x1 |
|
3x1 |
| 2 u |
4 u |
3 u |
The number of cranberry macarons is the repeated identity. Make the number of cranberry macarons the same. LCM of 1 and 2 is 2.
Total number of macarons
= 2 u + 4 u + 3 u
= 9 u
9 u = 72
1 u = 72 ÷ 9 = 8
Number of cranberry macarons
= 2 u
= 2 x 8
= 16
Answer(s): 16
