0.5 is a rational number. It can also be written as 1/2
Any real, rational number times something equals 200.In every case, the something is (200)/(the real rational number) .
Yes. Any irrational number can be divided by itself to produce 1, which is a rational number.
4.7 is already a rational number. If you mean as a mixed number, this is equal to 4 7/10 or four and seven tenths.
yes
A non-square rational number is a rational number that cannot be expressed as the square of any rational number. For example, ( \frac{2}{3} ) is a non-square rational number because there are no rational numbers whose square equals ( \frac{2}{3} ). In general, any rational number that does not have a perfect square as its numerator and denominator is considered a non-square rational.
Yes, the sum is always rational.

from another wikianswers page: say that 'a' is rational, and that 'b' is irrational. assume that a + b equals a rational number, called c. so a + b = c subtract a from both sides. you get b = c - a. but c - a is a rational number subtracted from a rational number, which should equal another rational number. However, b is an irrational number in our equation, so our assumption that a + b equals a rational number must be wrong.
Yes. Any irrational number can be divided by itself to produce 1, which is a rational number.
4.7 is already a rational number. If you mean as a mixed number, this is equal to 4 7/10 or four and seven tenths.
Yes, it equals 6/10.

Yes. 0.3 with a bar over it is 1/3, which is a rational number.

No. 3/(1/7) is a rational number. However, (1/7) cannot be used as an integer. Incidentally, the number equals 21.
n = 1
They are called conjugates.
