Oscar had
19 as many beads as Nick. Nick had thrice as many beads as Bryan. If Oscar had 54 beads fewer than Bryan,
- how many beads did Oscar have?
- how many beads did they have altogether?
(a)
Number of beads that Oscar had = 1 u
Number of beads that Nick had = 9 u
Number of beads that Bryan had = 9 u ÷ 3 = 3 u
Number of beads that Oscar had fewer than Bryan
= 3 u - 1 u
= 2 u
2 u = 54
1 u = 54 ÷ 2 = 27
Number of beads that Oscar had
= 1 u
= 27
(b)
Total number of beads that they had
= 1 u + 9 u + 3 u
= 13 u
= 13 x 27
= 351
Answer(s): (a) 27; (b) 351
