Paul had some marbles. He gave
23 of his marbles to Rael 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, Paul had 46 marbles.
- How many marbles did Paul give to his cousin?
- How many marbles did Paul have at first?
(a)
Fraction of his remaining marbles after he gave to his cousin
= 1 -
25=
35 35 of his remaining marbles = 46 - 7 = 39
15 of his remaining marbles = 39 ÷ 3 = 13
25 of his remaining marbles = 2 x 13 = 26
Number of marbles that Paul gave to his cousin = 26
(b)
55 of his remaining marbles = 5 x 13 = 65
Fraction of his total marbles after he gave to Rael
= 1 -
23=
13 13 of his total marbles = 65 - 4 = 61
33 of his total marbles = 3 x 61 = 183
Number of marbles that Paul had at first = 183
Answer(s): (a) 26; (b) 183
