If each of them gets 11 beads, there are 3 beads left.
If each of them takes 9 beads, there are 21 beads left.
- How many children are there?
- How many beads are there?
(a)
Big difference
= 21 - 3
= 18
Small difference
= 11 - 9
= 2
Number of children
= 18 ÷ 2
= 9
(b)
Total number of beads
= 9 x 11 + 3
= 99 + 3
= 102
Answer(s): (a) 9; (b) 102
