Well, I don't know.
Let's see . . .
To simplify any fraction, you divide both the numerator and denominator
by their greatest common factor. So we need to determine whether 49
and 98 have any common factors.
When you work it all out, it turns out that 49 is the greatest common factor
of 49 and 98, so you can divide top and bottom by 49. When you do that,
you have 1/2 .
