How do you find the answer to a division problem with a rational number?

You may or may not be able to. The diameter of a circle with circumference 10 cm is 10/pi, a division problem. But there is no answer using rational numbers.

A rational number can be expressed as a ratio p/q of two integers where q &gt; 0. Divide the numerator p by the denominator q. The answer is the decimal representation of the rational number.

The average of the two will be rational and it will be between them.

It is the number that youve hat to square to get to that number.

Find the arithmetic average of the two rational numbers. It will be a rational number and will be between the two numbers.

If the number can be expressed as a ratio of two integer (the second not zero) then the number is rational. However, it is not always a simple matter to prove that if you cannot find such a representation, then the number is not rational: it is possible that you have not looked hard enough!

The answer will depend on whether you want percentage equivalents of rational numbers or one rational number as a percentage of another.

The idea is to look for a rational number that is close to the desired irrational number. You can find rational numbers that are as close as you want - for example, by calculating more decimal digits.

The divisor in this division problem is 26.

3.1 is a rational number because it is a terminating decimal that can be expressed as an improper fraction in the form of 31/10

Add them together and divide by 2 will give one of the rational numbers between two given rational numbers.

Given a rational number, express it in the form of a ratio. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.

Your question looks like: x7 - 9x4 + 3x2 + 3. This problem cannot be solved using synthetic division alone--you need to know what to divide by. There are some ways to find possible solutions to try dividing by (Rational Roots Test &amp; Descartes' Rule of Signs), but I've done that for this problem, and none of the solutions are rational. I feel like you left out part of the question.

Yes it can be because a rational number is a number that can be written as a ratio with a fraction with denominator on top and numerator on bottom. You can turn the ratio into decimal or any ways you can and you can find it on a number line...

Irrationals differ from Rationals by definition. If a real number is not a Rational Number then it is Irrational. One way to find out if a number is either Rational or Irrational is to look at its decimal value. If the digits past the decimal point terminate then it is a Rational number. If the digits past the decimal point repeat the same digit forever, of if it repeats a sequence of digits over and over, then it is a Rational Number. If the digits past the decimal point do not repeat in any pattern, and do not stop, then it is an Irrational number. Another way to find out if a number is Rational or Irrational is if it can be exactly described by a fraction (ratio). If it is the same as some fraction, then it is a Rational Number. Irrationals cannot be exactly described as a fraction.

You use basic facts to do the division problem.

Let your sum be a + b = c, where "a" is irrational, "b" is rational, and "c" may be either (that's what we want to find out). In this case, c - b = a. If we assume that c is rational, you would have: a rational number minus a rational number is an irrational number, which can't be true (both addition and subtraction are closed in the set of rational numbers). Therefore, we have a contradiction with the assumption that "c" (the sum in the original equation) is rational.

If a decimal can be expressed as a fraction then it is a rational number as for example 0.75 = 3/4 Also, if the decimal ever ends, or is a never ending repeat of the same digit or group of them, then it's a rational number.

There exists infinite number of rational numbers between 0 &amp; -1.

There are an infinite number of rational numbers between any two rational numbers. And 2 and 7 are rational numbers. Here's an example. Take 2 and 7 and find the number halfway between them: (2 + 7)/2 = 9/2, which is rational. Then you can take 9/2 and 2 and find a rational number halfway: 2 + 9/2 = 13/2, then divide by 2 = 13/4. No matter how close the rational numbers become, you can add them together and divide by 2, and the new number will be rational, and be in between the other 2.
