Bryan has 100 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
= 100 + 80
= 180
(b)
Number of beads that Bryan has more than Adam
= 100 - 80
= 20
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
= 20 ÷ 2
= 10
(c)
Number of beads that Adam must get from Bryan
= Number of beads that Bryan must give to Adam
= 10
Answer(s): (a) 180; (b) 10; (c) 10
