Mrs Glen baked
13 as many chocolate chip biscuits as cranberry biscuits. She also baked
23 as many chocolate chip biscuits as blueberry biscuits. If she baked a total of 110 biscuits, how many chocolate chip biscuits did she bake?
| Chocolate Chip |
Cranberry |
Blueberry |
| 1x2 |
3x2 |
|
| 2x1 |
|
3x1 |
| 2 u |
6 u |
3 u |
The number of chocolate chip biscuits is the repeated identity. Make the number of chocolate chip biscuits the same. LCM of 1 and 2 is 2.
Total number of biscuits
= 2 u + 6 u + 3 u
= 11 u
11 u = 110
1 u = 110 ÷ 11 = 10
Number of chocolate chip biscuits
= 2 u
= 2 x 10
= 20
Answer(s): 20
