Answer 2

u need common denominator to add the numerators

Answer 3

I got the LCM by finding what 9 6 equates to, that is 54. Whatever I do to the bottom of the fraction I do t the top, so I multiplied the numerators the same way.

Answer 4

Now all you need to d is simplify and reduce.

Good, so you get \[\frac{51}{54}\] now divide both numerator and denominator by 3, and simplify.
