Bryan has 60 marbles.
Adam has 50 marbles.
- What is the sum of marbles?
- How many marbles must Bryan give to Adam so both have the same number of marbles?
- How many marbles must Adam get from Bryan so both have the same number of marbles?
(a)
Total sum of marbles
= 60 + 50
= 110
(b)
Number of marbles that Bryan has more than Adam
= 60 - 50
= 10
For both Bryan and Adam to have the same number of marbles, the extra marbles must be shared equally.
Number of marbles that Bryan must give to Adam
= 10 ÷ 2
= 5
(c)
Number of marbles that Adam must get from Bryan
= Number of marbles that Bryan must give to Adam
= 5
Answer(s): (a) 110; (b) 5; (c) 5
