Which of the following statements is false? if a number is a natural number, then it is rational. if a number is a whole number, then it is rational. if a number is a fraction, then it is rational. if a number is an integer, then it is irrational.

The number sets follow this inclusion scheme:

Which means that natural numbers are a subset of integer numbers, which are a subset of rational numbers, which are a subset of real numbers.

So, every natural number (i.e. 0,1,2,3,4,....) is in particular an integer.

Every integer(i.e. ...,-3,-2,-1,0,1,2,3,...) is in particular a rational number.

Every rational number (i.e. every ratio between integers) is in particular a real number.

Irrational numbers are real numbers that are not rational (which means that irrational numbers are .

So, the first option is true because

The second option is true because

The third option is true by definition: is the set of fraction (although we have to specify that the fraction must be between two integers)

But integers are not irrational, so the last one is false.

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
