The number of blueberry puffs Flynn baked was
47 of the total number of puffs. After baking another 168 blueberry puffs, the number of blueberry puffs became
67 of the total number of puffs. How many puffs did she bake at first?
|
Blueberry puffs |
Other puffs |
Total puffs |
Before |
4 u |
3 u |
7 u |
Change |
+ 168 |
|
|
After |
6x3 = 18 u |
1x3 = 3 u |
7x3 = 21 u |
The number of other puffs remains unchanged. Make the number of other puffs the same. LCM of 3 and 1 is 3.
Number of more blueberry puffs baked
= 18 u - 4 u
= 14 u
14 u = 168
1 u = 168 ÷ 14 = 12
Number of puffs that Flynn baked at first
= 7 u
= 7 x 12
= 84
Answer(s): 84
