# Ratios

##### Topic Notes

What are two-term and three term ratios? After watching this lesson, you will be able to answer this question by writing ratios in the lowest terms as well as in fraction and percent form. Practice your understanding by doing some real-life word questions too.

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.
