- 1 u = _____
Choose the person who has less stickers to be 1 u.
Adam has 10 less stickers than Bryan.
So, Adam has less stickers.
(a)
Number of stickers that Adam has = 1 u
(b)
Number of stickers that Bryan has = 1 u + 10
(c)
Total number of stickers
= 1 u + 1 u + 10
= 2 u + 10
(d)
Total number of stickers = 30
2 u + 10 = 30
2 u = 30 - 10 = 20
1 u = 20 ÷ 2 = 10
Answer(s): (a) 1 u; (b) 1 u + 10; (c) 2 u + 10; (d) 10
