Mrs Tommy baked
13 as many chocolate chip macarons as cheese macarons. She also baked
23 as many chocolate chip macarons as cranberry macarons. If she baked a total of 110 macarons, how many chocolate chip macarons did she bake?

1x2 |
3x2 |

2x1 |

3x1 |
2 u |
6 u |
3 u |
The number of chocolate chip macarons is the repeated identity. Make the number of chocolate chip macarons the same. LCM of 1 and 2 is 2.
Total number of macarons
= 2 u + 6 u + 3 u
= 11 u
11 u = 110
1 u = 110 ÷ 11 = 10
Number of chocolate chip macarons
= 2 u
= 2 x 10
= 20
Answer(s): 20
