- How many buttons did Rael give to his cousin?
- How many buttons did Rael have at first?
(a)
Fraction of his remaining buttons after he gave to his cousin
= 1 -
25=
35 35 of his remaining buttons = 37 - 7 = 30
15 of his remaining buttons = 30 ÷ 3 = 10
25 of his remaining buttons = 2 x 10 = 20
Number of buttons that Rael gave to his cousin = 20
(b)
55 of his remaining buttons = 5 x 10 = 50
Fraction of his total buttons after he gave to Glen
= 1 -
34=
14 14 of his total buttons = 50 - 4 = 46
44 of his total buttons = 4 x 46 = 184
Number of buttons that Rael had at first = 184
Answer(s): (a) 20; (b) 184
