Fill in the blanks.
Adam has eight times as many stickers as Bryan.
Adam gave 6 to Bryan.
In the end, Adam has six times as many stickers as Bryan.

1. Difference in the number of stickers between Adam and Bryan at first = _____ u
2. Difference in the number of stickers between Adam and Bryan in the end = _____ u
3. Difference in the number of stickers Adam has at first and in the end = _____ u
4. Difference in the number of stickers Bryan has at first and in the end = _____ u

	Adam	Bryan	Total
Before	8 x 7 = 56 u	1 x 7 = 7 u	9 x 7 = 63 u
Change	- 6	+ 6
After	6 x 9 = 54 u	1 x 9 = 9 u	7 x 9 = 63 u

(a)
Change X times into units.

There is an internal transfer of 6 stickers from Adam to Bryan.

The total remains unchanged.
LCM of 9 and 7 is 63.

Number of stickers that Adam gives to Bryan
= 56 u - 54 u
= 2 u

Difference in the number of stickers between Adam and Bryan at first
= 56 u - 7 u
= 49 u

(b)
Difference in the number of stickers between Adam and Bryan in the end
= 54 u - 9 u
= 45 u

(c)
Difference in the number of stickers that Adam has at first and in the end
= 56 u - 54 u
= 2 u

(d)
Difference in the number of stickers that Bryan has at first and in the end
= 9 u - 7 u
= 2 u

Answer(s): (a) 49; (b) 45; (c) 2; (d) 2
