Multiplication Property of Inequality for c > 0
Understand and apply Multiplication Property of Inequality for c > 0 in Grade 9 algebra. Use this rule to simplify, solve, and verify mathematical expressions efficiently.
Key Concepts
Property For every real number $a$ and $b$, and for $c 0$: If $a b$, then $ac bc$. If $a < b$, then $ac < bc$. Explanation Think of this as scaling up! If you have more cookies than your friend ($a b$) and you both get five times as many ($c=5$), you still have more cookies. Multiplying by a positive number keeps the relationship the same, so the inequality sign doesn't change. It’s a fair game! Examples To solve $\frac{1}{3}x \le 7$, multiply by 3: $(3)\frac{1}{3}x \le 7(3)$, so $x \le 21$. Since $8 5$, then $8(2) 5(2)$ because $16 10$.
