Mrs Howard baked
12 as many apricot wafers as cheese wafers. She also baked
34 as many apricot wafers as banana wafers. If she baked a total of 117 wafers, how many apricot wafers did she bake?
| Apricot |
Cheese |
Banana |
| 1x3 |
2x3 |
|
| 3x1 |
|
4x1 |
| 3 u |
6 u |
4 u |
The number of apricot wafers is the repeated identity. Make the number of apricot wafers the same. LCM of 1 and 3 is 3.
Total number of wafers
= 3 u + 6 u + 4 u
= 13 u
13 u = 117
1 u = 117 ÷ 13 = 9
Number of apricot wafers
= 3 u
= 3 x 9
= 27
Answer(s): 27
