The number of blueberry wafers Henry baked was
25 of the total number of wafers. After baking another 56 blueberry wafers, the number of blueberry wafers became
34 of the total number of wafers. How many wafers did she bake at first?

Blueberry wafers |
Other wafers |
Total wafers |
| Before |
2 u |
3 u |
5 u |
| Change |
+ 56 |
|
|
| After |
3x3 =
9 u |
1x3 =
3 u |
4x3 =
12 u |
The number of other wafers remains unchanged. Make the number of other wafers the same. LCM of 3 and 1 is 3.
Number of more blueberry wafers baked
= 9 u - 2 u
= 7 u
7 u = 56
1 u = 56 ÷ 7 = 8
Number of wafers that Henry baked at first
= 5 u
= 5 x 8
= 40
Answer(s): 40
