When dividing fractions and mixed numbers, the most important step is to convert the mixed number into a single fraction. E.g. 1, 1/3 should be written as 4/3.

try to divide both numerator and denominator by a number until both numbers are not decimals. example: 2/4 can be simplified to 1/2 by dividing by 2
Multiply the whole number times the fraction's denominator, and add the result to the existing numerator. Examples : 2 3/7 = [ (2x7) + 3] /7 = 17/7 3 and 7/10 = (10 * 3 + 7)/10 = 37/10 (Multiply fraction's denominator times whole number, add that product to fraction's numerator, and place over original fraction's denominator. )
No, -3 is a rational number. All fractions are rational along with all decimals that terminate or repeat. (this applies to both positive and negative numbers.)
The Density Property states that, between two rational numbers on a number line there is another rational number. Mark some fractions on a number line. No matter how dense the number line is, there still is another number between the two numbers.
Any fraction can be written in many different ways.For example, 1/2 of a cake is the same amount of cake as 4/8ths, or 8/16ths. 3/4 of 100 dollars is the same as 75/100ths of 100 dollars.We say that 1/2, and 4/8 and 8/16 are equivalent fractions. 3/4 and 75/100 are equivalent too.If you take any fraction and multiply both the top number and the bottom number by the same amount, the fraction means the same as before. It doesn't matter what that amount is, as long as it's the same.This also means that you can divide the top and bottom numbers by the same amount too. 12/18 = 6/9. We divided the top and bottom numbers by 2. But we can divide by 3 as well. 6/9 = 2/3. This is the simplest form we can write the fraction in.So to turn a fraction into its simplest form, you go on dividing the top and bottom numbers by whatever whole number you can until you can't divide any more.90/150 = 9/15 (dividing by 10)9/15 = 3/5 (dividing by 3)So 90/150 in its simplest form is 3/5
