What is the difference between 6500. and 6500? The first one would be considered to have a terminal decimal. This means that instead of simply writing the number as it is, a decimal is added to the end to represent significant figures (terminal decimals are most commonly used in scientific notation). Therefore, when 6500 would only be considered as to having 2 significant figures, 6500. has 4 significant figures.

What is a terminal decimal in math?
A decimal that does NOT recur to infinity. e.g. 3.2424 is a terminal decimal 3.242424.... is a recurring to infinity decinal. Note the use of three or more stops after the last (right hand) digit. e.g. Terminal decimals 3.1 3.12 4.156. 0.1234 et seq.,
Why is 0.57575757 irrational?
NO!!!! It is NOT irrational. Reason, it can be converted to a Ratio(fraction). How do I know??? You have not indicated that the decimals go to inifinity. There is a regular order in the digits. As given it is a terminal decimal 0.57575757 If it was an infinite decimal it should read 0.57575757... ( Note the dots that indicate it contiunes to infinity. As a terminal decimal its fraction is 57575757/100000000 Ugh!!!! As an infinite decimal it can be converted to a ratio(fraction) Hence Let P = 0.57575757... & 100P = 57.57575757.... Subtract 99P = 57 ( Notice the repeating decimals subtract to zero. P = 57/99 Cancel down by '3' P = 19/33 THe answer 0.575757... = 19/33 & 0.57575757 = 57575757/100000000

Is 6.2222 a rational number?
Yes!!! Because it can be converted to a fraction. However, is '6.2222' a terminal decimal or do you mean that it repeats to infinity. If it repeast to infinity it shoulkd be written as '6.2222....' Note the three or more dots after the last decimal digits. This indiv=cates to mathematicians that the deimal 'repeats to infinity'. In both cases they are RATIONAL numbers, because they can be both converted to a quotient/fraction.
