Writing style in fraction

[Yuseph]

Hey guys,

How would you write it ?
Since im a beginner i still havent seen how its usually written.

 

[skeeter]

I would change the mixed number to an improper fraction ...

[math]\dfrac{1}{3} \cdot \dfrac{7}{4}[/math]

Sorry pal that wasnt my question. I want to know which style is appropriate multiplication sign or parentheses. In that particular situation i mean. With a proper fraction multiplied by a mixed fraction.

The two formats are equally bad. Replace the mixed fraction with an improper fraction, and they become equally good.

If you must use mixed fractions, use them in final answers, not computations.

It depends on context.

As a statement of a problem in an elementary level class, you would probably see the multiplication sign; in starting your work in a problem of your own, either would be fine; but as others have indicated, in the middle of work in algebra (where a mixed number looks confusingly like a multiplication), it's best to avoid mixed numbers entirely.

But neither form is stylistically wrong in general. Both can be understood equally well, as long as the context is one in which mixed numbers are expected.
