Fill in the blanks.
Bryan and Adam have some stickers.
25 of Bryan's stickers is equal to
811 of Adam's stickers
Let
111 of Adam's stickers be 1 u.
- Number of stickers that Adam has = _____ u
- Number of stickers that Bryan has = _____u
- Total number of stickers = _____ u
- Difference in the number of stickers between Adam and Bryan = _____u
(a)
Make the numerators the same.
LCM of 2 and 8 = 8
25 of Bryan's stickers =
811 of Adam's stickers
2 x 4 5 x 4 of Bryan's stickers =
811 of Adam's stickers
820 of Bryan's stickers =
811 of Adam's stickers
Let
111 of Adam's stickers be 1 u.
1111 of Adam's stickers = 11 u
Number of stickers that Adam has = 11 u
(b)
25 of Bryan's sticker =
811 of Adam's stickers = 8 u
15 of Bryan's stickers = 8 ÷ 2 = 4 u
55 of Bryan's stickers = 4 × 5 = 20 u
Number of stickers that Bryan has = 20 u
(c)
Total number of stickers
= 11 u + 20 u
= 31 u
(d)
Difference in the number of stickers between Bryan and Adam
= 20 u - 11 u
= 9 u
Answer(s): (a) 11; (b) 20; (c) 31; (d) 9
