Mrs David baked
13 as many blueberry muffins as banana muffins. She also baked
27 as many blueberry muffins as apricot muffins. If she baked a total of 90 muffins, how many blueberry muffins did she bake?
Blueberry |
Banana |
Apricot |
1x2 |
3x2 |
|
2x1 |
|
7x1 |
2 u |
6 u |
7 u |
The number of blueberry muffins is the repeated identity. Make the number of blueberry muffins the same. LCM of 1 and 2 is 2.
Total number of muffins
= 2 u + 6 u + 7 u
= 15 u
15 u = 90
1 u = 90 ÷ 15 = 6
Number of blueberry muffins
= 2 u
= 2 x 6
= 12
Answer(s): 12
