How is a rational number that is not an integer different from a rational number that is an integer?

Rational that is an integer can be whole numbers and negative whole numbers
But, rationals include ALL fractions, which although includes all rational numbers, but includes other members like 1/2, 1/3 and so on

When you are doing fractions, all fractions can be Ratios, Percents, and decimals. So for example 3/4 is also 3:4, 75%, and .75. Integers are numbers that can be whole numbers if it isn't an integer then it isn't a whole number but there are different ways to find the answer to this problem. Sorry if this doesn't help. 

Start fraction 5 over 6 end fraction and 0.833...
