Bryan has 50 beads.
Adam has 20 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
= 50 + 20
= 70
(b)
Number of beads that Bryan has more than Adam
= 50 - 20
= 30
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
= 30 ÷ 2
= 15
(c)
Number of beads that Adam must get from Bryan
= Number of beads that Bryan must give to Adam
= 15
Answer(s): (a) 70; (b) 15; (c) 15
