3 u |
1 u |
The number of sweets that Jen had in the end is repeated. Make the number of sweets that Jen had in the end the same. LCM of 1 and 3 is 3.
Number of sweets that Wendy had less than Jen
= 18 u - 5 u
= 13 u
13 u = 65
1 u = 65 ÷ 13 = 5
Number of sweets that Jen had at first
= 18 u
= 18 x 5
= 90
Answer(s): 90
