The product of two rational numbers can always be written as
a. an irrational number.
b. a whole number.
c. an integer.
d. a fraction.

D. a fraction

Step-by-step explanation:

A rational number is a number that can be written as a fraction with an integer in the numerator and a natural number in the denominator.

To multiply two fractions, we just have to multiply the numerator of the first fraction with the numerator of the second one and the same with the denominators.  

Doing that, we get another fraction. Sometimes we can get an integer or a whole number, but we can always write it as a fraction.

Therefore, the correct answer is D.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
