Adam has 100 beads.
Bryan has 20 beads.
- What is the sum of beads?
- How many beads must Adam give to Bryan so both have the same number of beads?
- How many beads must Bryan get from Adam so both have the same number of beads?
(a)
Total sum of beads
= 100 + 20
= 120
(b)
Number of beads that Adam has more than Bryan
= 100 - 20
= 80
For both Adam and Bryan to have the same number of beads, the extra beads must be shared equally.
Number of beads that Adam must give to Bryan
= 80 ÷ 2
= 40
(c)
Number of beads that Bryan must get from Adam
= Number of beads that Adam must give to Bryan
= 40
Answer(s): (a) 120; (b) 40; (c) 40
