Adam has 170 beads.
Bryan has 80 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
= 170 + 80
= 250
(b)
Number of beads that Adam has more than Bryan
= 170 - 80
= 90
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
= 90 ÷ 2
= 45
(c)
Number of beads that Bryan must get from Adam
= Number of beads that Adam must give to Bryan
= 45
Answer(s): (a) 250; (b) 45; (c) 45
