Exercises Numbers, fractions and percents

Example 4.59 from Prealgebra, 4.4 Add and Subtract Fractions with Common Denominators

Add and Subtract Fractions with Common Denominators: example 4.59

Find the difference: $\frac{23}{24} - \frac{14}{24} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

$\frac{23}{24} - \frac{14}{24}$

Subtract the numerators and place the difference over the common denominator. $\frac{23 - 14}{24}$

Simplify the numerator. $\frac{9}{24}$

Simplify the fraction by removing common factors. $\frac{3}{8}$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Find the difference: $\frac{19}{28} - \frac{7}{28} .$
