what is the common denominator for 3,5, and 15 ? What can 3,5, and 15 all go into evenly ?

anonymous · Answer

isnt it 30?

texaschic101 · Answer

well, 30 is one of them, but it would be easier to find the lowest common denominator...there is one lower then 30.....can you find it ?

anonymous · Answer

give me a second to write this out

anonymous · Answer

15 :D

texaschic101 · Answer

you can use 30 if you wish, but you will just have to reduce at the end. Yes...15 is the LCD.
Now multiply the entire equation by 15.
15 (2/3) + 15(3m/5) = 15(31/15)

now what can you do with that

you need help ?

anonymous · Answer

yes  =.= i am so sorry i feel so stupid its been so long i havnt really praticed

texaschic101 · Answer

once you multiply by 15, you should get :
10 + 9m = 31 (subtract 10 from both sides)
9m = 31 - 10
9m = 21
m = 21/9 or 2 3/9 which reduces to 2 1/3
