Oliver had
19 as many stamps as Seth. Seth had thrice as many stamps as Vincent. If Oliver had 46 stamps fewer than Vincent,
- how many stamps did Oliver have?
- how many stamps did they have altogether?
(a)
Number of stamps that Oliver had = 1 u
Number of stamps that Seth had = 9 u
Number of stamps that Vincent had = 9 u ÷ 3 = 3 u
Number of stamps that Oliver had fewer than Vincent
= 3 u - 1 u
= 2 u
2 u = 46
1 u = 46 ÷ 2 = 23
Number of stamps that Oliver had
= 1 u
= 23
(b)
Total number of stamps that they had
= 1 u + 9 u + 3 u
= 13 u
= 13 x 23
= 299
Answer(s): (a) 23; (b) 299
