9-8.

Show your work as you complete each of the following problems.

1. $8 \frac { 1 } { 10 } \div 1 \frac { 1 } { 2 }$

This problem is very similar to 9-7. Refer to that problem if you are having difficulty starting this problem.

$5\frac{2}{5}$

2. $\frac { 5 } { 2 } \div \frac { 3 } { 3 }$

Since three-thirds is equal to one, you are actually dividing five-halves by one.

3. $\frac { 3 } { 5 } \cdot 1 \frac { 4 } { 7 }$

It may be best to change the mixed number into a fraction greater than one before you multiply.

$\frac{33}{35}$

4. $\frac { 0 } { 3 } \div \frac { 9 } { 7 }$

Look carefully at this problem.
Do you notice anything interesting?

Zero-thirds is equal to zero.
What happens when you divide zero by any number?
