Our Next Unit Is Rational Numbers. What are they? How do we use them?

A Rational Number is any number that can be expressed as the quotient a/b of two integers.

So A number that can be a fraction, an example would be maybe

Natural Numbers are first they are numbers that we use everyday like 1,2,3,4,5,6,7

Then it is Whole Numbers 0 and Natural numbers.

Then Itegers which are Whole Numbers and their opposites eg. -3,-2,-1,0,1,2,3

Then it Rational Numbers itegers that can be expressed as fractions.

After that Irrational numbers, numbers that can't be expressed as fractions. Eg PI.

Ok so, I hope i covered some major things.

Good job Shaneille! I like your use of colour. Thank you for explaining what rational numbers, natural numbers, whole numbers, integers what irrational numbers are. Your overall scribe is good but there is just one spelling mistake..buts its probably just a typo. If you wondering what the mistake is, Itegers is supposed to be integers. And again, good job(:
