Adam has 180 marbles.
Bryan has 50 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
= 180 + 50
= 230
(b)
Number of marbles that Adam has more than Bryan
= 180 - 50
= 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) 230; (b) 65; (c) 65
