The number 2.35 is already written as a decimal fraction.
Suppose x is a rational number and y is an irrational number.Let x + y = z, and assume that z is a rational number.The set of rational number is a group.This implies that since x is rational, -x is rational [invertibility].Then, since z and -x are rational, z - x must be rational [closure].But z - x = y which implies that y is rational.That contradicts the fact that y is an irrational number. The contradiction implies that the assumption [that z is rational] is incorrect.Thus, the sum of a rational number x and an irrational number y cannot be rational.

.1111 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
2.600 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 2600/1000. You can simplify this rational fraction if required. However, the simplified form will not show that the number is accurate to three decimal places.
The decimal shows a repeating pattern. Repeating decimals are rational.
yes, repeating decimals (those that have infinite - never ending - number of digits after the decimal point and these decimals show repeating pattern) are rational numbers, because they can be written as fractions.
Well, darling, that number you've thrown at me is 88 sextillion. Yes, you heard me right, sextillion. That's a whole lot of zeros, honey. Hope that clears things up for you!
BEL is simply the decimal equivalent of the number 7, and the function of BEL is to show the number 7.
If it can be expressed as a fraction then it is a rational number
It is a rational number that is 2/9 as a fraction
-12.02 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 -1202/100. You can simplify this rational fraction if you so wish.
88 = 88/1. The number can be expressed as a ratio of two integers and, therefore, it is a rational number.
Integers are counting numbers or include them. 1/2 is a rational number that is not a couinting number.
The decimal point is used to show that the number is not whole. Numbers after the decimal point show fractions of the number so there is more accuracy.
