Warren and Gabriel have 20 beads altogether. Warren has 2 more beads than Gabriel. Find the number of beads each boy has.
- Gabriel
- Warren
Number of beads that Gabriel has = 1 u
Number of beads that Warren has = 1 u + 2
Total number of beads
= 1 u + 1 u + 2
= 2 u + 2
2 u + 2 = 20
2 u = 20 - 2 = 18
1 u = 18 ÷ 2 = 9
(a)
Number of beads that Gabriel has
= 1 u
= 9
(b)
Number of beads that Warren has
= 1 u + 2
= 9 + 2
= 11
Answer(s): (a) 9; (b) 11
