Mrs Asher baked
13 as many vanilla shortbreads as banana shortbreads. She also baked
23 as many vanilla shortbreads as chocolate chip shortbreads. If she baked a total of 88 shortbreads, how many vanilla shortbreads did she bake?
| Vanilla |
Banana |
Chocolate Chip |
| 1x2 |
3x2 |
|
| 2x1 |
|
3x1 |
| 2 u |
6 u |
3 u |
The number of vanilla shortbreads is the repeated identity. Make the number of vanilla shortbreads the same. LCM of 1 and 2 is 2.
Total number of shortbreads
= 2 u + 6 u + 3 u
= 11 u
11 u = 88
1 u = 88 ÷ 11 = 8
Number of vanilla shortbreads
= 2 u
= 2 x 8
= 16
Answer(s): 16
