8-93.

Calculate each of the following quotients.

1. $7 \frac { 1 } { 4 } \div \frac { 3 } { 8 }$

Begin by rewriting the mixed number as a fraction greater than one.

$7\frac{1}{4}\div\frac{3}{8}=\frac{29}{4}\div\frac{3}{8}$

Calculate the quotient by multiplying by the multiplicative inverse.

$\frac{29}{4}\div\frac{3}{8} = \frac{29}{4}\cdot\frac{8}{3}$

Carry out the multiplication and then reduce the fraction to its simplified form.

$\frac{58}{3} = 19\frac{1}{3}$

1. $9.82\div0.2$

Solve through regular long division. Don't forget to count the decimal places and move the decimal point in the quotient!

1. $9 \frac { 9 } { 10 } \div 4 \frac { 4 } { 5 }$

Follow the process outlined in part (a).
