Grade 9 - Rational Numbers

Rational numbers: any number that can be written in the form m/n, where m and n are integers and n cannot equal zero.
Ex. 0.4, 4/7, -1.23
We will explore number lines and integers to determine which rational expression is larger.
Ex. Which rational number is larger? 1/4 or 3/4
Ex. Which rational number is larger? -2/3 or -3/2
Why?
What is the difference between an integer and a rational number? Integers are whole numbers like -3, -2, -1, +1, +2, +3. Rational numbers can have decimals like 1.4 and -2.3.
Without a calculator, estimate the answer. (5)(-3)/(-7) = -15/-7 = 2.1

Using the textbook, complete pg. 37-40 #3, 4ace, 5acegik, 6all, 7, 9ace, 10(only the ones that can be written as integers), 14, 15, 20, 21, 23acegi, 24(use a calculator and compute the final answer showing the steps).
Happy Calculating!
