Mrs Daniel baked
12 as many cranberry croissants as apricot croissants. She also baked
25 as many cranberry croissants as blueberry croissants. If she baked a total of 110 croissants, how many cranberry croissants did she bake?
Cranberry |
Apricot |
Blueberry |
1x2 |
2x2 |
|
2x1 |
|
5x1 |
2 u |
4 u |
5 u |
The number of cranberry croissants is the repeated identity. Make the number of cranberry croissants the same. LCM of 1 and 2 is 2.
Total number of croissants
= 2 u + 4 u + 5 u
= 11 u
11 u = 110
1 u = 110 ÷ 11 = 10
Number of cranberry croissants
= 2 u
= 2 x 10
= 20
Answer(s): 20
