Elijah had 345 marbles less than Winnie. Given that they have a total of 675 marbles,
- How many marbles did Winnie have?
- How many marbles did Elijah have?
(a)
Number of marbles that Winnie had = 1 u
Number of marbles that Elijah had = 1 u - 345
Total number of marbles
= 1 u + 1 u - 345
= 2 u - 345
2 u - 345 = 675
2 u = 675 + 345
2 u = 1020
1 u = 1020 ÷ 2 = 510
Number of marbles that Winnie had
= 1 u
= 510
(b)
Number of marbles that Elijah had
= 1 u - 345
= 510 - 345
= 165
Answer(s): (a) 510; (b) 165
