Answer:
Yes, 3.02859 is a rational number
Step-by-step explanation:
A rational number is a number represented by the quotient of two integers,
that is, in the form of a fraction.
For example: \(\frac{8}{7}\)
The number above is called numerator, and the number bellow is called denominator.
If the number cannot be represented with a fraction, we call it an irrational number.
Some examples:
1)Number: 1.25
In fraction: \(\frac{5}{4}\)
So, it is rational.
2)Number: 0.333333333.....
In fraction: \(\frac{1}{3}\)
So, it is rational.
3) Number: 2
In fraction: \(\frac{8}{4}\)
So, it is rational.
4) Number: 1,414213562 (\(\sqrt{2}\))
Cannot be expressed in fraction
So, it is irrational.
5) Number: 3,1415926535...(\(\pi )\)
Cannot be expressed in fraction
So, it is irrational.
To simply realize which number is rational and which is not, the following must be taken into account:
Rational numbers include:
integers: (2, 145, -48)
Exact decimal numbers (0.25,10.6, 7.09)
Pure periodic decimal numbers (0.999..., 0.171717)
Mixed periodic decimal numbers (3.25888..)
3.02859 is a rational number because it can be expressed as
\(\frac{302859}{100000}=3.02859\)
