Yes.
Why? Because a rational number is a number that can be written as a simple fraction.
Example 1.5 is a rational number because 1.5 = 3/2 (it can be written as a fraction)
Here are some more examples:
Number As a Fraction Rational?
5 5/1 Yes
1.75 7/4 Yes
.001 1/1000 Yes
0.111... 1/9 Yes
√2 ? NO !
Yes, 0.62 is a rational number. A rational number can be written as the quotient of two integers. 0.62 can be written as 62/100, which can be simplified to 31/50.
yes
Yes.
It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.
yes
No.
Yes.
31/1000
3.1 is a rational number because it is a terminating decimal that can be expressed as an improper fraction in the form of 31/10
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.
Yes, 0.62 is a rational number. A rational number can be written as the quotient of two integers. 0.62 can be written as 62/100, which can be simplified to 31/50.
No. It can be expressed as the ratio 31/10 and is, therefore, a rational number.
It is a rational number. It can be written as a fraction.
yes
