•  $\frac{1}{2}\ x\ \frac{1}{3}\ =\ \frac{1}{6}$  

•  $\frac{1}{2}\ -\ \frac{1}{3}\ =\ \frac{1}{6}$  

•  $\frac{1}{2}\ x\ \frac{1}{3}\ =\ \frac{1}{5}$  

•  $\frac{1}{3}\ -\ \frac{1}{2}\ =\ \frac{0}{1}$

• $28\ -\ 3\ \frac{1}{2}\ =\ 24\ \frac{1}{2}\ \ ;\ 24\ \operatorname{proj}ects$

• $28\ \div\ 3\ \frac{1}{2}\ =\ 8\ \operatorname{proj}ects$

• $3\ \frac{1}{2}\ \div\ 28\ =\ \frac{1}{8}\ \ of\ a\ \operatorname{proj}ect$

• $28\ x\ 3\ \frac{1}{2}\ =\ 98\ \operatorname{proj}ects$

• Subtraction

  $20\ -\ 2\ \frac{1}{2}\ =\ 17\ \frac{1}{2}\ cups$

• Division

  $20\ \div\ 2\ \frac{1}{2}\ =\ 8\ chips$
  

• $2\ \frac{1}{2}\ \div\ 20\ =\ \frac{1}{8}\ cups\ of\ chips$ Division

• Multiplication $20\ x\ 2\ \frac{1}{2}\ =\ 50\ chips$
