I'm not understanding ratios and i need with the meaning of this.

Hey there 
Let me help you out 

What are Ratio's? 

Ratios are relationships of numbers. They compare two different numbers. They tell how much of one object there is compared to another object. 

For example there are 5 red balls and 3 blue balls. 
The ratio for balls would be 5:3
5=red
3=blue 

hope this helps 

 

When understanding ratios, we need to know that it compares two quantities.

Remember this:- A ratio does NOT include units. It only compares two quantities.

Three ways to write a ratio:-

3/5      3:5       3 to 5

Example:- The ratio of boys to girls is 4 to 6.

Write a ratio.

4:6 or 4/6 or 4 to 6.
