Which expressions is below equal a rational number? choose all that apply

Step-by-step explanation:

we know that

A rational number is a number that can be written as a ratio of two integers

so

Verify each case

case A)

we know that

substitute

The number 0 is a rational number, because can be written as a ratio of two integers

Example

therefore

The expression is a rational number

case B)

Is not a rational number, because cannot be written as a ratio of two integers

case C)

Is not a rational number, because cannot be written as a ratio of two integers

case D)

The number 60 is a rational number, because can be written as a ratio of two integers

Example

therefore

The expression is a rational number

case E)

The number is a rational number, because can be written as a ratio of two integers

therefore

The expression is a rational number

A,D,E

Step-by-step explanation:

Rational number :That number which can be written as where q is not equal to zero and p,q are both integers.

We have to find which number is rational number

1.

0 is rational number by define of rational number .

Hence, option A is true.

B.

We know that is a irrational number when we multiply a irrational number with rational number then the number becomes irrational number

Where 3 is rational number and is a irrational number

Hence, the number is a irrational number not rational number.

Therefore, option B is not true.

C.

We know that is a irrational number

When we add rational number to irrational number then the number becomes irrational number .

So, is a irrational number.

Hence, option C is not true.

D.

=60

60 is a rational number because can be written as form.

Hence, option D is true.

E.

It is a rational number because it is in the form of .

Hence, option E is true.

it's both, now can you answer my most recent question?
