sometimes true (when the rational numbers are the same)
No
when you add mixed numbers you have a whole number but adding fraction does not.
All numbers with a finite number of decimal digits are rational. Some that infinitely many decimal digits are rational as well. If you mean to repeat the pattern, adding one more "1" every time, then no, it is not rational - rational numbers repeat the SAME sequence of digits over and over (for example, 0.1515151515...), at least eventually (they may start with some digits that are not part of the repeating part, such as 3.87112112112...).
How is doing operations (adding, subtracting, multiplying, and dividing) with rational expressions similar to or different from doing operations with fractions?If you know how to do arithmetic with rational numbers you will understand the arithmetic with rational functions! Doing operations (adding, subtracting, multiplying, and dividing) is very similar. When you areadding or subtracting they both require a common denominator. When multiplying or dividing it works the same for instance reducing by factoring. Operations on rational expressions is similar to doing operations on fractions. You have to come up with a common denominator in order to add or subtract. To multiply the numerators and denominators separated. In division you flip the second fraction and multiply. The difference is that rational expressions can have variable letters and powers in them.
A simple answer is they are merely numbers however there are many different properties to consider such as adding etc
Then you are adding two rational numbers with different signs! No big deal!
what is the rule in adding rational numbers
Never.
Subtraction is not commutative nor associative.
They are different in the same way that subtraction of integers is different from their addition.
There is only one type of rational number so there are no different types which you can add.
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.
By finding their common denominator & adding the top numbers of-the fractions. : )
No
A rational number can be stated in the form a/b where and b are integers. Adding or multiplying such numbers always gives another number that can be expressed in this form also. So it is also rational.
Wats are temples from South East Asia and, as far as I am aware, they do not dicatate any rules for adding rational numbers.
The value of the answer is the sum of the absolute values of the numbers and the sign of the answer is the same as that of the two numbers.
