Mrs Michael baked
13 as many apple croissants as apricot croissants. She also baked
27 as many apple croissants as blueberry croissants. If she baked a total of 105 croissants, how many apple croissants did she bake?
Apple |
Apricot |
Blueberry |
1x2 |
3x2 |
|
2x1 |
|
7x1 |
2 u |
6 u |
7 u |
The number of apple croissants is the repeated identity. Make the number of apple croissants the same. LCM of 1 and 2 is 2.
Total number of croissants
= 2 u + 6 u + 7 u
= 15 u
15 u = 105
1 u = 105 ÷ 15 = 7
Number of apple croissants
= 2 u
= 2 x 7
= 14
Answer(s): 14
