*Notes*

### When multiplying fractions with the different/unrelated denominators, you don’t have to do anything special. All you have to do is *numerator multiply by the numerator* and *denominator multiplied by denominator*.

### When dividing fractions with the different/unrelated denominators, it’s a little bit more complicated. What you have to do is *flip (find the inverse) the second fraction *then proceed as if your multiplying the fractions. *Numerator multiplied by the numerator and denominator multiplied by the denominator.*
