• Dividing: If there is a decimal on the outside of the division sign, you must move it first before you can start dividing.
• 575.82 ÷ 6.3• 91.4
• Multiplying: Multiply like normal and then count the decimal places in your problem and move the decimal to the right in your answer
• 7.85 3.4• 26.69

Inequalities• greater than >, less than <, greater than or
equal to ≥, less than or equal to ≤
• To solve an inquality, you solve it exactly like an equation (WYDTOSDTTO).
• 3x ≥ 27• x ≥ 9; any number 9 or greater
• To write an inequality from a statement, you must choose the key words and pick which symbol matches the key word• The cost of the shirt will be no more than
$10.
• s ≤ 10
