Gabriel had 372 stamps less than Zoe. Given that they have a total of 636 stamps,
- How many stamps did Zoe have?
- How many stamps did Gabriel have?
(a)
Number of stamps that Zoe had = 1 u
Number of stamps that Gabriel had = 1 u - 372
Total number of stamps
= 1 u + 1 u - 372
= 2 u - 372
2 u - 372 = 636
2 u = 636 + 372
2 u = 1008
1 u = 1008 ÷ 2 = 504
Number of stamps that Zoe had
= 1 u
= 504
(b)
Number of stamps that Gabriel had
= 1 u - 372
= 504 - 372
= 132
Answer(s): (a) 504; (b) 132
