The answer depends on the value of w, which is not specified.
The answer depends on the value of W.
w
It is kW/kY where k is any non-zero number.
12/15 is different.
Ah, math time, my favorite! To reduce the fraction w^2 + 5w + 6 over w^2 - w - 12, first factor both the numerator and the denominator. The numerator factors into (w + 2)(w + 3), and the denominator factors into (w + 3)(w - 4). Cancel out the common factor of (w + 3) in both the numerator and the denominator, leaving you with (w + 2) over (w - 4). Voilà!
It is W/100.
It is W/50.
The answer depends on W.
It is W/100. Depending on the value of W it may be possible to simplify the fraction
5.22 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, being a decimal, there is no simpler form. Its rational equivalent is 522/100 which can be simplified to 261/50.
It depends on the value of w.
