Adam has 170 marbles.
Bryan has 70 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
= 170 + 70
= 240
(b)
Number of marbles that Adam has more than Bryan
= 170 - 70
= 100
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
= 100 ÷ 2
= 50
(c)
Number of marbles that Bryan must get from Adam
= Number of marbles that Adam must give to Bryan
= 50
Answer(s): (a) 240; (b) 50; (c) 50
