Operations on rational numbers refer to the mathematical operations carrying out on two or more rational numbers. A rational number is a number that is of the form p/q, where: p and q are integers, q ≠ 0. Some examples of rational numbers are: 1/2, −3/4, 0.3 (or) 3/10, −0.7 (or) −7/10, etc.
We know about fractions and how different operators can be used on different fractions. All the rules and principles that apply to fractions can also be applied to rational numbers. The one thing that we need to remember is that rational numbers also include negatives. So, while 1/5 is a rational number, it is true that −1/5 is also a rational number. There are four basic arithmetic operations with rational numbers: addition, subtraction, multiplication, and division.
If the denominator is the same, you just add the numerators - just as with plain numbers.
The simple way: multiply the numerators to get the numerator, multiply the denominators to get the denominator. To get the preferred answer cancel common factors in the new numerator and denominator. But this can be tricky.
They are rational, if the numerator and denominator are integers. For example, -2 / 3 would be a rational number.They are rational, if the numerator and denominator are integers.

Whole numbers are rational numbers with a denominator of 1. The difference with general rational numbers is that the denominators are likely to be different and they must be made the same by converting the fractions into equivalent fractions with the same denominator before the addition can be done - by adding the numerators and keeping the denominator, and simplifying (if possible) the result. With whole numbers the denominators are already the same (as 1) and so the addition can be done straight away.
Yes. This is the same as asking for one rational number to be subtracted from another; to do this each rational number is made into an equivalent rational number so that the two rational numbers have the same denominator, and then the numerators are subtracted which gives a rational number which may possibly be simplified.
Convert all the rational numbers to order into equivalent fractions with the same denominator; then they can be ordered by putting the numerators in order from least to greatest. ------------ You can also convert all the numbers to decimals ... this is actually a special case of "equivalent fractions".
All integers are rational numbers.
A fraction is a ratio of two numbers. Fractions are typically ratios of integers (where the denominator is not zero), which makes them "rational." The root word of rational is ratio. You could have pi/2, or sqr(2)/2, both of which are fractions that are NOT rational.
process by which a fraction containing radicals in the denominator is rewritten to have only rational numbers in the denominator.
They are numbers in which the denominator does not go into the numerator a whole number of times.
First, unmix the numbers ((denominator times whole number plus numerator) over denominator). Then multiply the numerators together and the denominators together. The numerator of the product is the product of the numerators of all of the multiplicands, and the denominator of the product is the product of the denominators of all of the multiplicands. Third, simplify.
The fact that they can be expressed as a ratio of two whole numbers (with the denominator being non-zero).
