Question

Somebody plz help me

Answer 1

Answer:

I am sorry thats a lot to type out.

Step-by-step explanation:

I will say that to know if its rational, you have to see if the integer can be written in a fraction (like 0.333, 89/10, -4, 0)

Answer 2

Answer:

Whole numbers: 3, $\sqrt{4}$, $\frac{49}{7}$, zero

Integer but not whole: -100, -34, -4, -$\frac{8}{4}$

Rational number: 9.23456, $\frac{1}{2}$, $\frac{89}{10}$, 0.333_

Irrational number: $\pi$, 0.456783_, $\sqrt{8}$

Step-by-step explanation:

Whole number is any number that does not have a decimal and is not negative. $\sqrt{4}$ = 2. $\frac{49}{7}$ = 7. 0 is not negative and does not have a decimal so it is also a whole number.

Integers are any number that does not have a decimal and can be both positive or negative. -$\frac{8}{4}$ = -2.

A rational number can have a decimal but the decimal digits must terminate or the digit must repeat.  $\frac{1}{2}$ is 0.5.  $\frac{89}{10}$ is 8.9 and 0.333_ repeats the digit 3 so it is rational.

An irrational number can have a decimal and the decimal digits must list on forever or not repeat. $\pi$ is naturally an irrational number as it does not repeat and it spreads on forever. 0.456783_ does not repeat and goes on forever due to the dash at the back. $\sqrt{8}$ is also not rational.
