Here is one example, if you are reading an on line document and you see 5 of 500 it means you are on page 5 of 500 pages.
If you mean 4/5 of 500 then it is 400
100 + 300 + 500 + 500 + 600 = 2000. Then divide by 5 to get 400. The mean of these five numbers is 400.
If you mean 10% then it is 500
500 + 50 + 5
If you mean meters then 5 meters = 500 centimeters
5/500 is likely the strength of the medication. For example. Lortab 5/500 would contains hydrocodone and acetaminophen in a ratio of 5mg of hydrocodone to 500mg of acetaminophen.
5 Mg of Hydrocodone and 500 Mg of Acetaminophen(Tylenol)
0.002
500
1k = 1000500k = 5 00 000
500 million = 500,000,000 or 5 x 10^8 It can also be called half a billion.
The answer for 5 times 500 is 2500.
