Is -11.7 an irrational number?
NO it is not irrational, that is to say it IS rational. If you can write a number as ratio of integers, it is rational. -11.7 can certainly be written as a ratio of integers.
How would you convince a fellow student that the number 0.57 is a rational number?
0.57 can be written as 57/100. 57 and 100 are both integers and therefore 0.57 can be written as a ratio of 2 integers. A number that can be written as a ratio of two integers is a rational number because the word rational comes from ratio.
Numbers that can be written as the ratio of two integers are called what numbers?
Rational
Is -0.15 a rational number?
Yes, -0.15 is a rational number. A rational number is any number that can be expressed as a ratio of two integers, where the denominator is not zero. In this case, -0.15 can be expressed as -15/100, which is a ratio of two integers (-15 and 100). Therefore, -0.15 is a rational number.
Square of a rational number is rational?
Sure. Let's take an example with numbers instead of variables. 8/9 is a rational number - the ratio of two integers. If you square it, you get (8/9)2 = 82/92 = 64/81; that is, if you square each integer, you get an integer again. Therefore, the resulting number is rational again - a number that can be expressed as the ratio of two integers. Replace with any other integers; you will still have a ratio of integers if you square it.
A rational number can be written as a?
a ratio of integers
Is a rational number a ratio of any two integers?
Not quite. A rational number is a ratio and each rational number is a ratio of specific pairs of integers - not ANY two integers. And, of course, 0 is not allowed on the denominator.
A number that cannot be expressed as a ratio of two integers?
A number that cannot be expressed as the ratio of two integers is known as an irrational number.
What is a ratio of two integers when the denominator congruent zero?
The ratio is not defined.
What is any number that can be expressed as a ratio of two integers?
Any number that can be expressed as the ratio of two integers is a rational number.
Is -11.7 an irrational number?
NO it is not irrational, that is to say it IS rational. If you can write a number as ratio of integers, it is rational. -11.7 can certainly be written as a ratio of integers.
How do you express a numbers a ratio of two integers?
The ratio of two integers, p and q where q is not 0, can be expressed as p:q or p/q.
A rational number is a number that can be written as a what?
ratio of two integers, p/q where q is not equal to zero.
Can ratios be irrational?
Yes. But if you have a ratio of two integers, the ratio will be rational by definition.
A rational number can be written as the ratio of one?
No. It is a ratio of TWO - not ONE - integers.
Is the ratio of two integers aways positive?
No
Which set is the intersection of integers and rational numbers?
The intersection of integers and rational numbers is the set of integers. Integers are whole numbers that can be positive, negative, or zero, while rational numbers are numbers that can be expressed as a ratio of two integers. Since all integers can be expressed as a ratio of the integer itself and 1, they are a subset of rational numbers, making their intersection the set of integers.
