Question

Somebody plz help me

Answer 1

I am sorry thats a lot to type out.

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

Whole numbers: 3,
`√(4)`,
`(49)/(7)`, zero

Integer but not whole: -100, -34, -4, -
`(8)/(4)`

Rational number: 9.23456,
`(1)/(2)`,
`(89)/(10)`, 0.333_

Irrational number:
`\pi`, 0.456783_,
`√(8)`

Explanation:

Whole number is any number that does not have a decimal and is not negative.
`√(4)` = 2.
`(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. -
`(8)/(4)` = -2.

A rational number can have a decimal but the decimal digits must terminate or the digit must repeat.
`(1)/(2)` is 0.5.
`(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.
`√(8)` is also not rational.
