How are rational numbers written in diffrent forms?

A rational number is a number that can be written as an integer over an integer.

The are square roots that are perfect squares.

They can be written as a fraction that terminates or repeats.

Step-by-step explanation:

Integers are whole number and their opposites:

...-3, -2 -1 0 1 2 3....

is not a rational number because when it is written as a decimal, it does not repeat or terminate.

is a rational number because it is equal to 4.  It is a perfect square.

is not a perfect square so it is not rational.

ian gonna lie that is way to much

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
