6-17.

Simplify the following expressions.

1. $1 \frac { 1 } { 2 } + 2 \frac { 1 } { 8 }$

First convert these into fractions greater than one.

Next, find a common denominator and compute the sums.

$3\frac{5}{8}$

1. $\frac{4}{5}-\frac{2}{3}+\frac{1}{6}$

Find a common denominator among these three fractions.

Multiply each fraction by a Giant One to convert each fraction to ensure a common denominator.

Compute the sum and differences.

1. $5\frac{3}{5}-1\frac{4}{5}$

See part (a). Note these fractions already have a common denominator.

$3\frac{4}{5}$
