Whats the difference between an irrational number and a rational number?

An irrational number is one that has no defined ending. EVER. Meaning that as far as we calculate, there will always be infinite more numbers extending away. A rational number is one that has a defined ending, or at least one that we can see. There are two main types: a repeating decimal, or a terminating decimal. An example of a repeating decimal would be 2/3, or 0.6666666 repeating. This number goes on forever, but we know what each number is, so that's okay. An example of a terminating decimal is one that just...ends, such as 1/2, which in decimal form is just 0.5.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

9 sandwiches per hour

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
