| After |
6 u |
6 u |
6 u |
18 u |
Total number of lollipops
= 10 u + 7 u + 1 u
= 18 u
Number of lollipops that each had in the end
= 18 u ÷ 3
= 6 u
Number of lollipops that Natalie gave to Rachel and Sabrina
= 10 u - 6 u
= 4 u
4 u = 8
1 u = 8 ÷ 4 = 2
Total number of lollipops
= 18 u
= 18 x 2
= 36
Answer(s): 36
