Ivan had 333 beads less than Natalie. Given that they have a total of 669 beads,
- How many beads did Natalie have?
- How many beads did Ivan have?
(a)
Number of beads that Natalie had = 1 u
Number of beads that Ivan had = 1 u - 333
Total number of beads
= 1 u + 1 u - 333
= 2 u - 333
2 u - 333 = 669
2 u = 669 + 333
2 u = 1002
1 u = 1002 ÷ 2 = 501
Number of beads that Natalie had
= 1 u
= 501
(b)
Number of beads that Ivan had
= 1 u - 333
= 501 - 333
= 168
Answer(s): (a) 501; (b) 168
