Fraction Definitions

There are a few basic fraction definitions you need to be aware of before we start looking at things you can do with them.

In English . . .

The position of negative signs sometimes causes a little confusion. Ultimately, it doesn't matter whether a negative sign goes in the numerator, the denominator or in front of the fraction.

$$\frac{-3}{4} = \frac{3}{-4} = -\frac{3}{4}$$
