After |
6 x 3 = 18 u |
1 x 3 = 3 u |
5 x 3 = 15 u |
(a)
Change X times into units.
The difference in the number of stickers that Bryan and Adam have at first and in the end is the same.
LCM of 3 and 5 is 15.
Difference in the number of stickers between Bryan and Adam
= 20 u - 5 u
= 15 u
(b)
Number of stickers that Bryan and Adam had in the end
= 18 u + 3 u
= 21 u
(c)
Number of stickers that Bryan gives away
= 20 u - 18 u
= 2 u
(d)
2 u = 16
1 u = 16 ÷ 2 = 8
Answer(s): (a) 15 ; (b) 21; (c) 2 ; (d) 8
