[tex] = \frac{(8.2 - 0.2) \div 0.08 \times 4}{(4 \frac{5}{9} + 6 \frac{1}{9} ) \times \frac{5}{3} } = \frac{8 \div 0.08 \times 4}{10 \frac{2}{3} \times \frac{5}{3} } = \frac{100 \times 4}{ \frac{32}{3} \times \frac{5}{3} } = \frac{400}{ \frac{160}{9} } = 400 \div \frac{160}{9} = 400 \times \frac{9}{160} = \frac{90}{4} = 22 \frac{2}{4} = 22 \frac{1}{2} [/tex]
