Gabriel had
18 as many beads as Riordan. Riordan had twice as many beads as Perry. If Gabriel had 117 beads fewer than Perry,
- how many beads did Gabriel have?
- how many beads did they have altogether?
(a)
Number of beads that Gabriel had = 1 u
Number of beads that Riordan had = 8 u
Number of beads that Perry had = 8 u ÷ 2 = 4 u
Number of beads that Gabriel had fewer than Perry
= 4 u - 1 u
= 3 u
3 u = 117
1 u = 117 ÷ 3 = 39
Number of beads that Gabriel had
= 1 u
= 39
(b)
Total number of beads that they had
= 1 u + 8 u + 4 u
= 13 u
= 13 x 39
= 507
Answer(s): (a) 39; (b) 507
