Question

8/5x + 3/x?

Answer 1

do you know how to find the common denominator? if you are unsure, does this at least sound like something familiar?

Answer 2

No, i don't but yes it does sound familiar

Answer 3

ok so you know how 1/1 is the same as 2/2? the way you get 2/2 is you multiplied the top by 2 and the bottom by 2, and it does not change your answer which is 1. the same works with 8/5x + 3/x . in order to add fractions the bottom needs to be the same. 1/2 + 1/2 = (1+1)/2
lets start off with the bottoms of each fraction
8/5x and 3/x what could you do to the right side to make the bottom match the left side?

Answer 4

incase i run out of time
you can multiply the right side by 5/5 which turns it into 15/5x
now you can add
8/5x+15/5x do you know what this gives you? and are you understanding what is going on?

Answer 5

is it 23/5x?

Answer 6

it is! but do you understand how we got 15/5x? and also why we needed to do that?
