You write the two numbers, with a colon in between, for example:
8 : 6
This can be treated as a fraction; it can also be written as a fraction. Specifically, the ratio can be simplified (or expanded) the same way you simplify a fraction; in this case, you can divide both numbers by 2 to get:
4 : 3

What is the relationship between ratios fractions and percents?
They are all different ways of representing the same thing: a relationship between two numbers.
What numbers represent irrational numbers?
These are the numbers which cannot be expressed as ratios of two integers.
Is a ratio a comparison between two ratios?
A ratio is a comparison between two values. The values can be integers or fractions (ratios).
Why are some numbers irrational?
There are numbers which cannot be expressed as ratios of two integers. These are called irrational numbers.
The relationship between two ratios is a .?
proportion
How do you decide when to compare numbers using ratios rather by finding the difference of the two numbers?
Finding the difference between two numbers involves rationalising them
Is there a statistical test to assess the difference between two ratios. I have numbers which are ratios and want to test whether there is a statistical difference between them?
You can use the z test for two proportions. The link below will do this test for you.
What is the relationship between ratios and fractions?
They are all different ways of representing the same thing: a relationship between two numbers.
How do you find arithmetic mean between two numbers?
Add the two numbers and divide by two, or find the number which is halfway between the two numbers.

Is a ratio a comparison between two ratios?
A ratio is a comparison between two values. The values can be integers or fractions (ratios).
How do you insert rational numbers between two rational numbers?
Find the arithmetic average of the two rational numbers. It will be a rational number and will be between the two numbers.
How can ratios be used to compare two numbers?
Only 2
How do you find the median with two numbers?
To find the median with two numbers, do as you would to find the "average" or the "mean" by finding the sum between the two numbers and dividing the sum (or total) by two.
Why are some numbers irrational?
There are numbers which cannot be expressed as ratios of two integers. These are called irrational numbers.
When do two ratios form a proportion?
When both can multiply its comparisons to when both ratios share the exact same numbers.
