Exercises Numbers, fractions and percents

Example 4.60 from Prealgebra, 4.4 Add and Subtract Fractions with Common Denominators

Add and Subtract Fractions with Common Denominators: example 4.60

Find the difference: $\frac{y}{6} - \frac{1}{6} .$

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

$\frac{y}{6} - \frac{1}{6}$

Subtract the numerators and place the difference over the common denominator. $\frac{y - 1}{6}$

The fraction is simplified because we cannot combine the terms in the numerator.

Your turn

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

Find the difference: $\frac{x}{7} - \frac{2}{7} .$
