How do you reduce fractions if one number is odd?

The parity (odd or even) of a number has no relevance in reducing fractions. What is required is to find the highest common factor between the numerator and denominator. Clearly, if the numerator and denominator are bot even then 2 is a common factor and so it must be possible to reduce the fraction. The highest common factor or even a common factor may not be so obvious when both numerator and denominator are odd.For example, 21/91 = (3*7)/(13*7) = 3/13

Are the factors of an odd number always odd?

Yes. An even number is defined as being evenly divisible by 2 (no fractional answers, only integers). If an odd number has an even factor, then because of the above definition, this odd number must have a factor of 2. But you will be hard pressed to find an odd number that is a multiple of 2, because that is already the definition of an even number. So, odd numbers cannot have even factors and thus odd numbers always have odd factors.
