The best method to measure the thickness of a quarter is (C) Centimeters.
This is because the thickness of a quarter is very small and thus bigger units such as meters and kilometers will not be convenient. Centimeters is the best unit.
Let's work out the process to find the numerator:
(x+2)/2 - (x+1)/3x Factor using the LCD, 6x
3x(x+2)/6x - 2(x+1)/6x
(3x² + 6x - 2x - 2)/6x
= (3x² + 4x - 2)/6x
Answer is 3x² + 4x - 2
Hopefully I did this correct, Not to good with math c':
Answer: Amount that they paid in 2007 is 1.01 millions.
