1). Quick check:
Any number that you can write down completely with digits is a rational number.
So yes, it is.
2). Formal analysis:
A rational number is a number that can be written as the ratio of two integers.
375 is the ratio of 375 to 1 ( 375/1 ) .
So yes, it is.
375 is not prime. 375 = 3 * 5 * 5 * 5
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, it is irrational.
It is a rational number. It can be written as a fraction.
375 is a composite number
375 is not prime. 375 = 3 * 5 * 5 * 5
Any number to the power 1 is that number, thus 375^1 = 375.
yes
375 millionths as a number is: 0.000375
Is 12.05 a rational number or irrational number?
1.96 is a rational number
It is a rational number, as it can be written as a fraction.
Yes, the sum is always rational.
There is no such thing as a number that is both rational and irrational. By definition, every number is either rational or irrational.
