5-8.

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.

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 parts (a) and (b).

$3\frac{5}{8}$
