3x7 = 21 u |
4x7 = 28 u |
7x7 = 49 u |
Number of candy canes that John had at first in percentage
= 100% - 60%
= 40%
40% =
40100 =
25 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 7 and 7 is 49.
Number of candy canes that Luke gave to John
= 35 u - 28 u
= 7 u
7 u = 287
1 u = 287 ÷ 7 = 41
Number of candy canes that John had in the end
= 21 u
= 21 x 41
= 861
Number of candy canes that Luke had in the end
= 28 u
= 28 x 41
= 1148
Answer(s): (a) 861; (b) 1148
