Bobby and Ian have 12 beads altogether. Bobby has 2 more beads than Ian. Find the number of beads each boy has.
- Ian
- Bobby
Number of beads that Ian has = 1 u
Number of beads that Bobby has = 1 u + 2
Total number of beads
= 1 u + 1 u + 2
= 2 u + 2
2 u + 2 = 12
2 u = 12 - 2 = 10
1 u = 10 ÷ 2 = 5
(a)
Number of beads that Ian has
= 1 u
= 5
(b)
Number of beads that Bobby has
= 1 u + 2
= 5 + 2
= 7
Answer(s): (a) 5; (b) 7
