The number of cheese puffs Dylan baked was
35 of the total number of puffs. After baking another 35 cheese puffs, the number of cheese puffs became
45 of the total number of puffs. How many puffs did she bake at first?

Cheese puffs |
Other puffs |
Total puffs |
| Before |
3 u |
2 u |
5 u |
| Change |
+ 35 |

| After |
4x2 =
8 u |
1x2 =
2 u |
5x2 =
10 u |
The number of other puffs remains unchanged. Make the number of other puffs the same. LCM of 2 and 1 is 2.
Number of more cheese puffs baked
= 8 u - 3 u
= 5 u
5 u = 35
1 u = 35 ÷ 5 = 7
Number of puffs that Dylan baked at first
= 5 u
= 5 x 7
= 35
Answer(s): 35
