Fill in the blanks.
Adam has ten times as many stickers as Bryan.
Adam gave 119 to Bryan.
In the end, Adam has thrice 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	10 x 4 = 40 u	1 x 4 = 4 u	11 x 4 = 44 u
Change	- 119	+ 119
After	3 x 11 = 33 u	1 x 11 = 11 u	4 x 11 = 44 u

(a)
Change X times into units.

There is an internal transfer of 119 stickers from Adam to Bryan.

The total remains unchanged.
LCM of 11 and 4 is 44.

Number of stickers that Adam gives to Bryan
= 40 u - 33 u
= 7 u

Difference in the number of stickers between Adam and Bryan at first
= 40 u - 4 u
= 36 u

(b)
Difference in the number of stickers between Adam and Bryan in the end
= 33 u - 11 u
= 22 u

(c)
Difference in the number of stickers that Adam has at first and in the end
= 40 u - 33 u
= 7 u

(d)
Difference in the number of stickers that Bryan has at first and in the end
= 11 u - 4 u
= 7 u

Answer(s): (a) 36; (b) 22; (c) 7; (d) 7
