| Before |
5x4 =
20 u |
3 u |
| Change |
- 4x4 =
- 16 u |
- 2 u |
| After |
1x4 =
4 u |
1 u |
Comparing Opal
and Parry in the end |
4 u |
1 u |
The number of lollipops that Opal had in the end is repeated. Make the number of lollipops that Opal had in the end the same. LCM of 1 and 4 is 4.
Number of lollipops that Opal had more than Jean
= 20 u - 3 u
= 17 u
17 u = 153
1 u = 153 ÷ 17 = 9
Number of lollipops that Jean had at first
= 3 u
= 3 x 9
= 27
Answer(s): 27
