There are 1000000 micrograms in one gram. Therefore, 2 grams is equal to 2 x 1000000 = 2000000 micrograms.
2,000,000 in expanded form = (2 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
305000000 x 2000000 = 610000000000000
15 x 1000000 = 15,000,000
1000000 + 2000000 = 3,000,000

There are 1000000 micrograms in one gram. Therefore, 2 grams is equal to 2 x 1000000 = 2000000 micrograms.
2 percent of 2000000 = 40000 2% of 2000000 = 2% * 2000000 = 2%/100% * 2000000 = 0.02 * 2000000 = 40000
There are 1000000 milligrams in one kilogram. Therefore, 2000000 milligrams is equal to 2000000/1000000 = 2 kilograms.

00002/2000000 = 2/2000000 = 0.000001
2,000,000 in expanded form = (2 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
1 kilometre = 1000000 millimetres so 2 km = 2*1000000 = 2000000 millimetres. Simple!
305000000 x 2000000 = 610000000000000
If you are talking about a function in a variable (lets say f(x)=1/x) then it probably means that as x gets bigger and bigger, the function f(x) starts to settle around a certain number, ie: f(x) is the same for two really big numbers that are different. With f(x)=1/x we have f(1000000)=1/1000000=0.000001 and f(2000000)=1/2000000=0.0000005 Which are both VERY, VERY close to 0. SO in this example the expression (f(x)=1/x) is approaching a given value of 0.
