- How many cards did Eric give to his cousin?
- How many cards did Eric have at first?
(a)
Fraction of his remaining cards after he gave to his cousin
= 1 -
38=
58 58 of his remaining cards = 22 - 7 = 15
18 of his remaining cards = 15 ÷ 5 = 3
38 of his remaining cards = 3 x 3 = 9
Number of cards that Eric gave to his cousin = 9
(b)
88 of his remaining cards = 8 x 3 = 24
Fraction of his total cards after he gave to Henry
= 1 -
23=
13 13 of his total cards = 24 - 4 = 20
33 of his total cards = 3 x 20 = 60
