what is the ratio 3.5 to .25

Hey Aziz.

I've also found out that you can use \div to get a divided by sign in LaTeX.

So, you could display it like you did:

$$\frac{\frac{7}{2}}{\frac{1}{4}}$$

Or, you can also do:

$$\frac{7}{2} \div \frac{1}{4}$$

The way you did it is perfectly fine, I just thought I'd let you know. :)

3.5 : 0.25

7/2 : 1/4

We can write it as $$\frac{\frac{7}{2}}{\frac{1}{4}} = \frac{7}{2}*{\frac{4}{1} = \frac{28}{2} = \mathbf{14}.$$

Notice, if you multiply both sides by 4 --> 3.5(4) : 0.25(4) --> 14 : 1 --> 14/1 --> 14.

Both ways provide you with the same answer.

Thanks

That's good (looks better, too). Thanks for letting me know, Ninja.
