What is a rational number

A rational number is a number that can be expressed as the quotient (i.e. ratio or fraction) of two integers. ( Integers are rational since any integer, n ,can be written as n/1 )

Rational numbers are numbers that can be expressed as fractions whereas irrational numbers cannot be expressed as fractions
A rational number is a number that terminates or ends. As in a perfect square like: 144; 36; 625 etc.

<><><><><>

More specifically, a rational number is a number that can be expressed as the ratio of two integers, where the denominator is not zero. 1.37, for instance, is rational because it can be expressed as 137 / 100.
It is any whole number even if it's a negative number
Any number that can be expressed as a fraction is a rational number whereas irrational numbers can't be expressed as a fractions.
In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number.

What is the product of a whole number

The product of a whole number with a whole number is a whole number. A whole number is an integer ( a counting number).

Is 42 a rational number

yes any number that that can be made into a fraction is a rational number.

42= 42/1 so it is a rational number

Is 0 a rational number

Zero is a rational number. Rational numbers are numbers that can be represented by the division of two integers. Zero is zero divided by anything besides zero, so zero is rational.

Is the product of a rational number and a rational number a rational number

yes

Is 3.25 an integer or decimal

What is the phone number of the Mayville Library in Mayville

The sum of a rational and irrational number must be an irrational number.

Is 0.05 a rational or irrational number

It is a rational number.

Is .085 a rational number or irrational number

It is rational.

Is 9.565565556 rational

9.565565556 = 9565565556/1000000000 = 2391391389/250000000

So it is rational.

However, if you mean 9.565565556... where it continues with one more 5 than last time followed by a 6 and so on forever, then no, it is not a rational.

-----------------------------------------------------------------------------------------

The decimal form of a rational number either terminates or continues with the same one or more digits repeating, eg 1.5, 1.333..., 1.1818181..., 1.1666..., 1.1565656... are all rational numbers.

If the decimal does not terminate nor continue forever with the same repeating digit(s) then the number is irrational.

9.565565556 as written terminates and so it a rational number.

9.565565556... does not terminate nor does it continue with the same repeating digits (as an extra 5 is inserted before the next 6), so it it irrational.
