Good Hub. I'm sure this will help many people.

i was wondering how to solve two math problems:

1. 71/6 - 4 5/9

2. 13/5 + 29/10 + 3

1) first u need to change the mixed fraction

ie, 4 5/9 to be (4*5+9)/9 = (20+9)9 = 29/9

then, 71/6 + 29/9

here u have to find the LCM of 6,9

which is 18

I am so sorry, I made a mistake....this is the correct one1) first u need to change the mixed fraction

ie, 4 5/9 to be (4*9+5)/9 = (36+5)9 = 41/9

then, 71/6 + 41/9

here u have to find the LCM of 6,9

which is 18you have to multiply each fractional number with 18 and then divide complete with 18..ie with LCM

so (71/6 * 18 + 41/9 *18)/18= (71*3+41*2)/18= (213+82)/18=295/18=16.39

Um...How do you add three fraction together? please tell me! :'(

how do i do this problem 6 5/9 + 6 5/12 + 2 5/18
