Using V = lwh, what is an expression for volume of the following rectangular prism? 5/2x+8. 12/x. X+4/4. Answer A.) 15/2x
2 answers:
Step 1: Substitute the expression for l, w and h in the given volume formula.
Step 2: Simplify the expression by multiplying the fraction.
When multiplying fractions we need to multiply the numerator with numerator and denominator with denominator.
Factor 2x+8 in the denominator
Cancel the common factors in the numerator and denominator.

Answer to the first problem is 3 3/9
Reasoning:
To do these equations, you must change the mixed numbers into just fractions. I will do the first problem :)
2 divided by 3 2/3.
The first step in solving this equation is changing 3 2/3 back into a fraction.
To do this, do the denominator (3) times the whole number (also 3) and then add the numerator (2). 3 x 3 = 9. 9 is now your numerator and 3 is your denominator. 9/3
After this you want to put 10/1 MULTIPLIED by 3/9 (when dividing fractions you must flip the second fraction AND THEN MULTIPLY)
So 10/1 MULTIPLIED by 3/9 = 30/9
It then wants us to simply our answer. To do this, divide 30/9 by 9. You’ll get 3 3/9 as your answer for question 1!
