They are irrational numbers.
Yes. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
4.5 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Yes, it can be expressed as a ratio of two integers: -1086 / 10 or -543/5
A quotient of two numbers cannot have a denominator which is zero: such a fraction is not defined.
all of them. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Because that is the definition of irrational numbers: They are the numbers that cannot be written as a ratio of two integers! A fraction is a ratio of two integers.
Yes. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
4.5 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
1 is rational. Rational numbers are numbers that can be written as a fraction. Irrational Numbers cannot be expressed as a fraction.
Any number that cannot be written as a fraction of two integers (...-3,-2,-1,0,1,2,3,...) is irrational.
No, 25 is a rational number; it is an integer, and all integers are rational.
Yes, it can be expressed as a ratio of two integers: -1086 / 10 or -543/5
14 is rational. Rational numbers are numbers that can be written as a fraction. Irrational Numbers cannot be expressed as a fraction.
31 is rational. All integers are rational since they can be expressed as a fraction of integers. 31 = 31/1 = 62/2 = 93/3, etc.
A quotient of two numbers cannot have a denominator which is zero: such a fraction is not defined.
all of them. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
No, only rational numbers can be written as a ratio of two integers (the second being non-zero). The majority of real numbers are irrational and they cannot be so written.
