Solving inequalities with fractions is easy when applying the rules presented in this video. • When you add or subtract the same number from each side of an inequality, the relationship between the two sides does not change. • When you multiply or divide each side of an inequality by a positive number, the relationship between the left side and the right side does not change. • When you multiply or divide each side of an inequality by a negative number, the relationship between the left side and the right side reverses. The above rules can be summarized in the following six formulas: If m < n, then m+p < n+p If m < n, then m-p < n-p If m < n and p > 0, then mp < np If m < n and p < 0, then mp > np If m < n and p > 0, then m / p < n / p If m < n and p < 0, then m / p > n / p Watch the following videos to learn how to apply the above rules.
