- How many pens did Ryan give to his cousin?
- How many pens did Ryan have at first?
(a)
Fraction of his remaining pens after he gave to his cousin
= 1 -
38=
58 58 of his remaining pens = 22 - 7 = 15
18 of his remaining pens = 15 ÷ 5 = 3
38 of his remaining pens = 3 x 3 = 9
Number of pens that Ryan gave to his cousin = 9
(b)
88 of his remaining pens = 8 x 3 = 24
