0.444444444 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 444444444/1000000000. You can simplify this rational fraction if you so wish.
3.1 repeating, as a rational fraction is 28/9.
Yes - any proper fraction x/y is a rational number. Expressed as a decimal, this is equal to 0.4 recurring (that is, 0.44444...)
Yes. Any rational number divided by another rational number is also rational.
Yes it is a rational number because it can be expressed as 10/9 as an improper fraction
Any number that can be written as a fraction is rational -- therefore, 4/9 squared is rational (it can still be written as a fraction even if you multiply it by itself).
2.25 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 225/100. You can simplify this rational fraction if you require.
9/7 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
0.444444444 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 444444444/1000000000. You can simplify this rational fraction if you so wish.
No. sqrt(4/9) = 2/3 is rational. sqrt(0.64) = 0.8 = 4/5 is rational.
-1/9 is rational because it can be expressed as a fraction (ratio).
81 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
It is equivalent to 8/18 or 12/27. It cannot be simplified into a rational #
3/4 is a rational number because it can be written as a fraction. Even a big, clunky fraction like 7,324,908/56,003,492 is rational, simply because it can be written as a fraction.
If there are no numbers after the 9 it is rational
The number 0.444444 is a rational number. It is equivalent to 111111/250000, which, by definition of rational numbers, is rational. The number 0.444... (repeating) is also rational because it can be represented by the fraction 4/9. The number 0.444444 is a rational number because a rational number is a nnumber that can be expressed in the form of a fraction.
