Reggie had some marbles. He gave
23 of his marbles to Paul and bought 4 new marbles. After that, he gave
25 of his remaining marbles to his cousin and bought another 7 new marbles. In the end, Reggie had 43 marbles.
- How many marbles did Reggie give to his cousin?
- How many marbles did Reggie have at first?
(a)
Fraction of his remaining marbles after he gave to his cousin
= 1 -
25=
35 35 of his remaining marbles = 43 - 7 = 36
15 of his remaining marbles = 36 ÷ 3 = 12
25 of his remaining marbles = 2 x 12 = 24
Number of marbles that Reggie gave to his cousin = 24
(b)
55 of his remaining marbles = 5 x 12 = 60
Fraction of his total marbles after he gave to Paul
= 1 -
23=
13 13 of his total marbles = 60 - 4 = 56
33 of his total marbles = 3 x 56 = 168
Number of marbles that Reggie had at first = 168
Answer(s): (a) 24; (b) 168
