Jack and John have 18 beads altogether. Jack has 6 more beads than John. Find the number of beads each boy has.
- John
- Jack
Number of beads that John has = 1 u
Number of beads that Jack has = 1 u + 6
Total number of beads
= 1 u + 1 u + 6
= 2 u + 6
2 u + 6 = 18
2 u = 18 - 6 = 12
1 u = 12 ÷ 2 = 6
(a)
Number of beads that John has
= 1 u
= 6
(b)
Number of beads that Jack has
= 1 u + 6
= 6 + 6
= 12
Answer(s): (a) 6; (b) 12
