Bryan has 140 beads.
Adam has 80 beads.
- What is the sum of beads?
- How many beads must Bryan give to Adam so both have the same number of beads?
- How many beads must Adam get from Bryan so both have the same number of beads?
(a)
Total sum of beads
= 140 + 80
= 220
(b)
Number of beads that Bryan has more than Adam
= 140 - 80
= 60
For both Bryan and Adam to have the same number of beads, the extra beads must be shared equally.
Number of beads that Bryan must give to Adam
= 60 ÷ 2
= 30
(c)
Number of beads that Adam must get from Bryan
= Number of beads that Bryan must give to Adam
= 30
Answer(s): (a) 220; (b) 30; (c) 30
