Adam has 160 marbles.
Bryan has 100 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 + 100
= 260
(b)
Number of marbles that Adam has more than Bryan
= 160 - 100
= 60
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
= 60 ÷ 2
= 30
(c)
Number of marbles that Bryan must get from Adam
= Number of marbles that Adam must give to Bryan
= 30
Answer(s): (a) 260; (b) 30; (c) 30
