How do you know when two fractions are equal?
If the denominators (bottom numbers) are not equal, making equivalent fractions of them so that the denominators are equal. With the denominators equal if the numerators (top numbers) are equal, then the fractions are equal.
How do rational numbers equal rational decisions?
They do not. There is no relationship between rational numbers and rational decisions.
Why can't the denominators of rational expressions be zero How can we find the domain of a rational function?
Rational expressions are fractions and are therefore undefined if the denominator is zero; the domain of a rational function is all real numbers except those that make the denominator of the related rational expression equal to 0. If a denominator contains variables, set it equal to zero and solve.
Why does the definition of rational numbers state that b the denominator of the rational number ab cannot be equal?
I think it says a little more than that. b, the denominator of the rational number a/b, cannot be equal to zero because division by zero is undefined.
Difference between rational and irrational?
Rational numbers can be expressed in the form p/q (where q is not equal to zero). Irrational numbers cannot be expressed in this form. For example, the square root of 2 cannot be expressed as p/q.
Why in rational numbers q is not equal to 0?
The denominator of any number cannot be zero because division by zero is not defined.
Is 18 rational or irrational?
irrational
What are rational numbers and how are they used?
A rational number is a number that can be written in the form a/b, where "a" and "b" are integers and b is not equal to zero. For example, whole numbers are rational numbers.
What is anouther name for rational and irrational numbers?
Another name for 'rational' is "numbers that are equal to the ratio of two whole numbers". Another name for 'irrational' is "numbers that are not equal to the ratio of any two whole numbers".
What can the denominator of a rational expression never equal?
It cannot be zero.
What If the denominator is not the same?
Multiply the denominators to equal numbers, then multiply by the same number for the numerator. Then solve.
What are rational numbers and why are they important?
Rational numbers are ratios of two integers (the second of which is not zero). They are important if any number needs to be divided into equal parts.
