Julian had
112 as many cards as Ian. Ian had four times as many cards as Fred. If Julian had 78 cards fewer than Fred,
- how many cards did Julian have?
- how many cards did they have altogether?
(a)
Number of cards that Julian had = 1 u
Number of cards that Ian had = 12 u
Number of cards that Fred had = 12 u ÷ 4 = 3 u
Number of cards that Julian had fewer than Fred
= 3 u - 1 u
= 2 u
2 u = 78
1 u = 78 ÷ 2 = 39
Number of cards that Julian had
= 1 u
= 39
(b)
Total number of cards that they had
= 1 u + 12 u + 3 u
= 16 u
= 16 x 39
= 624
Answer(s): (a) 39; (b) 624
