Julie made 84 more apple wafers than cream wafers. After she gave away
35 of the apple wafers and
14 of the cream wafers, there were an equal number of apple wafers and cream wafers left. How many apple wafers did she give away?
|
Apple wafers |
Cream wafers |
Difference |
Before |
5x3 = 15 u |
4x2 = 8 u |
7 u |
Change |
- 3x3 = - 9 u |
- 1x2 = - 2 u |
|
After |
2x3 = 6 u |
3x2 = 6 u |

Fraction of apple wafers left
= 1 -
35 =
25Fraction of cream wafers left
= 1 -
14 =
34The number of apple wafers and cream wafers in the end is the same. Make the numerators the same. LCM of 3 and 2 is 6.
25 of apple wafers =
34 of cream wafers
615 of apple wafers =
68 of cream wafers
Number of more apple wafers than cream wafers at first
= 15 u - 8 u
= 7 u
7 u = 84
1 u = 84 ÷ 7 = 12
Number of apple wafers that Julie gave away
= 15 u - 6 u
= 9 u
= 9 x 12
= 108
Answer(s): 108
