Adam has 160 marbles.
Bryan has 30 marbles.
- What is the sum of marbles?
- How many marbles must Adam give to Bryan so both have the same number of marbles?
- How many marbles must Bryan get from Adam so both have the same number of marbles?
(a)
Total sum of marbles
= 160 + 30
= 190
(b)
Number of marbles that Adam has more than Bryan
= 160 - 30
= 130
For both Adam and Bryan to have the same number of marbles, the extra marbles must be shared equally.
Number of marbles that Adam must give to Bryan
= 130 ÷ 2
= 65
(c)
Number of marbles that Bryan must get from Adam
= Number of marbles that Adam must give to Bryan
= 65
Answer(s): (a) 190; (b) 65; (c) 65
