In this lesson, we will learn:

- Ratios With Decimals
- Ratios With Fractions
- Ratios in Different Units
- Application of Ratios

__Notes:__- A ratio should always be in its simplest/most reduced form (no common factors).
- The values in a ratio should always be integers if possible.
- A ratio can be scaled up/down by multiplying/dividing the ratio numbers by the same value. This process is called scaling, and the value used for scaling is called the scale factor.
