2.2 Rational Numbers

What are rational numbers? Any number than can be expressed as the ratio of two numbers – A fraction

We can turn whole numbers into fractions by putting them “over” 1. We can turn decimals into fractions by moving the decimal place and putting it “over” a multiple of 10.

Show that each can be written as the ratio of two integers

Making an Improper Fraction Get MAD M – Multiply the whole number by the denominator A - Add the numerator D – Divide by the original denominator
