4.1 is the ratio of 41 to 10 ... completely rational.
1). Quick check:Any number that you can completely write with digits is a rational number.So yes, -41 is rational.2). Formal mathematical analysis:Any number that can be written as the ratio of two integers is rational.-41 is the ratio of -41 and 1.So yes, -41 is rational.
41/9 is a rational number because all fractions are rational numbers
41 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
41 is an integer and not a fraction. However, it can be expressed in rational form as 41/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
Yes.
Yes.
Yes.
All integers and ratios between two integers are rational numbers. They are defined as p/q where p and q are integers and q is not 0. Therefore -41 is a rational number (and a negative integer as well).
Any terminating decimal is rational since it can be express as a fraction. Recurring decimals are also rational. E.g 3.456 = 3456/1000 or 4.555... = 41/9
Yes because 0.164 can be expressed as a fraction in the form of 41/250
0.205 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its equivalent, in rational form, is 205/1000. You can simplify this rational fraction if you so wish.
