The number of chocolate chip wafers Asher baked was
47 of the total number of wafers. After baking another 45 chocolate chip wafers, the number of chocolate chip wafers became
34 of the total number of wafers. How many wafers did she bake at first?

Total wafers |
| Before |
4 u |
3 u |

| 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 chocolate chip wafers baked
= 9 u - 4 u
= 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Number of wafers that Asher baked at first
= 7 u
= 7 x 9
= 63
Answer(s): 63
