The number of cherry wafers Henry baked was
25 of the total number of wafers. After baking another 48 cherry wafers, the number of cherry wafers became
23 of the total number of wafers. How many wafers did she bake at first?

Cherry wafers |
Other wafers |
Total wafers |
| Before |
2 u |
3 u |
5 u |
| Change |
+ 48 |

| After |
2x3 =
6 u |
1x3 =
3 u |
3x3 =
9 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 cherry wafers baked
= 6 u - 2 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Number of wafers that Henry baked at first
= 5 u
= 5 x 12
= 60
Answer(s): 60
