Question

How do you add
3/w+6 + 7/3w (those are fractions)

Answer 1

16/3w+6

Answer 2

how did you get that answer?

Answer 3

9/3w+6+7/3w

Answer 4

so you would multiply the first problems by 3?
to get the 9 /3w+6

Answer 5

what do you mean?

Answer 6

isnt that how you got 9/3w+6

Answer 7

3/w extend with 3

Answer 8

You need a common denominator of 3w(w + 6)

Answer 9

yes

Answer 10

Multiply the first fraction by 3w/3w which would equal
3(3w) = 9w over 3w(w + 6)

Answer 11

Multiply the second fraction by (w + 6)/(w + 6)

7(w + 6)/ 3w(w + 6) = 7w + 42 over 3w(w + 6)

Answer 12

yes so easy

Answer 13

Now you have a common denominator

9w + 7w + 42
-------- -----------
3w(w + 6) 3w(w + 6)

Answer 14

Add the top

16w + 42
---------
3w(w + 6)

Answer 15

can you simplify that answer?

Answer 16

resoult will be the same

Answer 17

You could take out a 2
2(8w + 21)
---------
3w(w + 6)

But that is as far as you can go.
