Tim had
16 as many cards as Simon. Simon had twice as many cards as Charlie. If Tim had 76 cards fewer than Charlie,
- how many cards did Tim have?
- how many cards did they have altogether?
(a)
Number of cards that Tim had = 1 u
Number of cards that Simon had = 6 u
Number of cards that Charlie had = 6 u ÷ 2 = 3 u
Number of cards that Tim had fewer than Charlie
= 3 u - 1 u
= 2 u
2 u = 76
1 u = 76 ÷ 2 = 38
Number of cards that Tim had
= 1 u
= 38
(b)
Total number of cards that they had
= 1 u + 6 u + 3 u
= 10 u
= 10 x 38
= 380
Answer(s): (a) 38; (b) 380
