Some children share some beads.
If each of them gets 11 beads, there are 2 beads left.
If each of them takes 9 beads, there are 22 beads left.
- How many children are there?
- How many beads are there?
(a)
Big difference
= 22 - 2
= 20
Small difference
= 11 - 9
= 2
Number of children
= 20 ÷ 2
= 10
(b)
Total number of beads
= 10 x 11 + 2
= 110 + 2
= 112
Answer(s): (a) 10; (b) 112
