ok, i'm having problems figuring out how to add these fractions, here's an example: 5 7/16-4 1/19-9 3/17 = ? pleeeez help!!!!!

• fractions -

I would change each mixed fraction as follows to a fraction:
5 7/16 = (5*16)+7 = 87/16
4 1/19 = (4*19)+1 = 77/19
9 3/17 = (9*17)+3 = 156/17

Then find the lowest common decnominator and go from there.

that's the problem i'm having now, i can't for the life of me find the common denominators, i have never felt more stupid in my life!!

When all else fails, you can always use 16*17*19. That may not be the lowest but it will always work. The final answers may be reducible.

A suggestion is to go and google how to find a common denominator in fractions

click on the first site on the list and it should help you with the lowest common denominator

hope it helps =D
