Evaluate the expression using properties of numbers. Name the property used in each step.
Bingel [31]

The properties are listed in the following order:

  1. <em>Given</em>
  2. <em>Conversion from mixed numbers into rational numbers / Associative property</em>
  3. <em>Addition of fractions with different denominators</em>
  4. <em>Mutiplication of fractions</em>
  5. <em>Associative property / Existence of multiplicative inverse / Modulative property / Definition of division</em>
<h3>How to simplify a product of rational numbers</h3>

Herein we are in front of a product of three <em>rational</em> numbers, that is, numbers of the form m / n, where m, n are integers and n ≠ 0. We need to apply definition and theorems from algebra to simplify a given number, whose procedure is shown in detail:

(2 3 / 4) · (1 1 / 8) · 32             Given

(2 + 3 / 4) · (1 + 1 / 8) · 32       Conversion from mixed numbers into rational numbers

(11 / 4) · (9 / 8) · 32                  Addition of fractions with different denominators

(99 / 32) · 32                          Mutiplication of fractions

99                                           Associative property / Existence of multiplicative inverse / Modulative property / Definition of division / Result

How do you solve and graph inequalities
Goshia [24]

Well, there can be three different steps.

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
