John had 383 marbles less than Vanessa. Given that they have a total of 699 marbles,
- How many marbles did Vanessa have?
- How many marbles did John have?
(a)
Number of marbles that Vanessa had = 1 u
Number of marbles that John had = 1 u - 383
Total number of marbles
= 1 u + 1 u - 383
= 2 u - 383
2 u - 383 = 699
2 u = 699 + 383
2 u = 1082
1 u = 1082 ÷ 2 = 541
Number of marbles that Vanessa had
= 1 u
= 541
(b)
Number of marbles that John had
= 1 u - 383
= 541 - 383
= 158
Answer(s): (a) 541; (b) 158
