First would you be able to find a LCD? least common denominator? what can 5,9, and 7 go into?

breathlessreaper · Answer

you know what, theres a much easier way to do this. Here, 
$$\frac{ 4 }{ 5 }$$ 

what is 4 divided by 7?
It would = 0.80...

Now do that for the others. Get the decimal forms.

breathlessreaper · Answer

$$\frac{ 4 }{ 5 } = 0.80$$

$$\frac{ 7 }{ 9 } = 0.78$$

$$\frac{ 6 }{ 7 } = 0.86$$

Your lowest fraction being 
7/9

then 
4/5

then
6/7 being the greatest

There's at least two other ways to do it. One of which doesn't necessarily require a calc or a pencil and paper to do for single digit fractions.
