Total |
Before |
1x11 = 11 u |
4x11 = 44 u |
5x11 = 55 u |

+ 280 |
- 280 |

After |
5x5 = 25 u |
6x5 = 30 u |
11x5 = 55 u |
Number of candy canes that George had at first in percentage
= 100% - 75%
= 25%
25% =
25100 =
14 The total number of candy canes at first and in the end remains unchanged. Make the total number of candy canes the same. LCM of 11 and 5 is 55.
Number of candy canes that Fred gave to George
= 44 u - 30 u
= 14 u
14 u = 280
1 u = 280 ÷ 14 = 20
Number of candy canes that George had in the end
= 25 u
= 25 x 20
= 500
Number of candy canes that Fred had in the end
= 30 u
= 30 x 20
= 600
Answer(s): (a) 500; (b) 600
