Fill in the blanks with units (Eg 1 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have 90 beads.
Bryan has 40 more beads than Adam.
- Number of beads that Bryan has = _____
- Number of beads that Adam has = _____
- Total number of beads = _____
- 1u = _____
Choose the person who has less beads to be 1 u.
Bryan has 40 more beads than Adam.
So, Adam has less beads.
(a)
Number of beads that Bryan has = 1 u + 40
(b)
Number of beads that Adam has = 1 u
(c)
Total number of beads
= 1 u + 40 + 1 u
= 2 u + 40
(d)
Total number of beads = 90
2 u + 40 = 90
2 u = 90 - 40 = 50
1u = 50 ÷ 2 = 25
Answer(s): (a) 1 u + 40 or 40 + 1 u; (b) 1u; (c) 2 u + 40 or 40 + 2 u; (d) 25
