Answer 1

Show me where you are stuck.

You need to find a common denominator first for problem 3.

Answer 2

ok

Answer 3

are one of them 6

Answer 4

6 and 9 are denominators, but you can't add numerators if the denominators aren't the same.

if you add 2/5 to 2/5 you get 4/5

you cannot add 2/5 to 4/15 so you need to find a common denominator

if you multiply 2/5 by 3/3

you get 6/15 so now you can add 6/15 and 4/15 to get 10/15

then you should simpify

Answer 5

ok

Answer 6

someone help pls

Answer 7

I am going to show you an easy way to break this kind of problem!

(5/6) + (4/9) =

your donamintor is not common

you need to multiply them together.

(9*5+6*4)/(6*9)

1. multiply the donamintor
2.take the result of donamintor and divided on the first term
3.and multiply by the nominator
4. do the same method for the other nominator.
