Henry had 387 beads less than Betty. Given that they have a total of 633 beads,
- How many beads did Betty have?
- How many beads did Henry have?
(a)
Number of beads that Betty had = 1 u
Number of beads that Henry had = 1 u - 387
Total number of beads
= 1 u + 1 u - 387
= 2 u - 387
2 u - 387 = 633
2 u = 633 + 387
2 u = 1020
1 u = 1020 ÷ 2 = 510
Number of beads that Betty had
= 1 u
= 510
(b)
Number of beads that Henry had
= 1 u - 387
= 510 - 387
= 123
Answer(s): (a) 510; (b) 123
