Answer 5

Between 16 and 8, the LCM is 16. Between x^2 and x^2 the LCM is x^2. So the LCM of 16x^2 and 8x^2 is 16x^2.

Answer 6

So i would multiply 5 by 2x^2?

Answer 7

Now you need to have the LCM as the denominator of both fractions. 16x^2 is already the denominator of the first fraction. Now you need to multiply the second fraction by 2/2 to get the LCM on the second fraction.
