- How many coins did John give to his cousin?
- How many coins did John have at first?
(a)
Fraction of his remaining coins after he gave to his cousin
= 1 -
59=
49 49 of his remaining coins = 23 - 7 = 16
19 of his remaining coins = 16 ÷ 4 = 4
59 of his remaining coins = 5 x 4 = 20
Number of coins that John gave to his cousin = 20
(b)
99 of his remaining coins = 9 x 4 = 36
Fraction of his total coins after he gave to Andy
= 1 -
23=
13 13 of his total coins = 36 - 4 = 32
33 of his total coins = 3 x 32 = 96
Number of coins that John had at first = 96
