Question

Which of the following numbers are rational, pie,0.7,and 0.333....

Answer 1

Rational numbers are numbers that can be expressed as a fraction. pi is irrational. 0.7 can be written as 7/10 so it is rational. 0.3333... is irrational because it cannot be expressed as a fraction.

Answer 2

Answer:

0.7 and 0.333... are rational.

Step-by-step explanation:

Given some numbers pie,0.7,and 0.333....

we have to find the numbers which are rational.

Rational numbers are the numbers which can be expressed in the form of $\frac{p}{q}$, where q≠0.

Irrational numbers are those which cannot be expressed in the form of $\frac{p}{q}$, where q≠0 and have an infinite non-repeating number of digits to right of decimal point.

The value of π is 3.14159265...

which is irrational as it is non-terminating without repetition.

$0.7=\frac{7}{10}$

which shows the above rational.

Now, 0.333... which is non-terminating but repeating.

Hence, rational.

Here, pi is irrational. 0.7  is rational. 0.3333... is rational because it cannot be expressed as a fraction.
