Mrs Flynn baked
12 as many apricot biscuits as cranberry biscuits. She also baked
27 as many apricot biscuits as chocolate chip biscuits. If she baked a total of 104 biscuits, how many apricot biscuits did she bake?

Chocolate Chip |
1x2 |
2x2 |

2x1 |

7x1 |
2 u |
4 u |
7 u |
The number of apricot biscuits is the repeated identity. Make the number of apricot biscuits the same. LCM of 1 and 2 is 2.
Total number of biscuits
= 2 u + 4 u + 7 u
= 13 u
13 u = 104
1 u = 104 ÷ 13 = 8
Number of apricot biscuits
= 2 u
= 2 x 8
= 16
Answer(s): 16
