Three fourths of a number is -27 . what is the number

The answer is -36

Step-by-step explanation:

3/4 of -36 is -27

Let x be the number  

3/4 of x = -27

Means

(3/4)(x)= -27

3x/4= -27

Multiply by 4 both sides

(4)(3x/4)=(-27)(4)

Cancel out 4 from Right hand side and multiply 4 on left hand side

3x=-108

Divide by 3 both sides

3x/3=-108/3

Cancel out 3 from Right hand side

x=-36

Number is -36

Have a great day!
