Yes, any integer over any other integer (except zero) is always a rational number.
It is equal to 21/2 which is a rational number
Any addition, subtraction, multiplication, or division of rational numbers gives you a rational result. You can consider 8 over 9 as the division of 8 by 9, so the result is rational.
21/3 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
7 over 8, which can be written as 7/8, is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are integers, and the denominator is not zero. Since 7 and 8 are both integers, and 8 is not zero, 7/8 is a rational number.
Any fraction involving whole numbers is RATIONAL.
Any number that is presented as an integer "over" (aka divided by) an integer is automatically a rational number - that's what the definition of a rational number is.
no it is not
ANY number that you can write as a fraction (with whole numbers top and bottom) is rational.
Because it can be expressed as a fraction in the form of 8/21
Rational.
Rational.
It is equal to 21/2 which is a rational number
8/23 is a rational number because all fractions and integers are rational numbers
5 over 8 is a rational number.
Any addition, subtraction, multiplication, or division of rational numbers gives you a rational result. You can consider 8 over 9 as the division of 8 by 9, so the result is rational.
21/3 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
.4/.8 is the same as 1/2 which is a rational number
