8-98.

Calculate each of the following products.

1.  $\frac { 1 } { 8 } \cdot \frac { 8 } { 1 }$

Multiply the numerators by one another and the denominators by one another.

$\left(\frac{1}{8}\right)\left(\frac{8}{1}\right)=\frac{(1)(8)}{(8)(1)}$

Simplify the fraction.

$\frac{8}{8}=1$

$1$

1.  $\frac { 3 } { 4 } \cdot \frac { 4 } { 3 }$

Follow the same steps as in part (a).

$1$

1.  $\frac { 2 } { 3 } \cdot \frac { 3 } { 2 }$

Parts (c) and (d) are very similar to part (a).

1.  $7 \cdot \frac { 1 } { 7 }$

1. What do the products in parts (a) through (d) have in common?
