Question

( 3/9 + 32/9 ) : 8/9 − 18/8?

Answer 1

$(\frac{3}{9} + \frac{32}{9}) \div \frac{8}{9} - \frac{18}{8} = \\ \frac{35}{9} \times \frac{9}{8} - \frac{18}{8} \\ \frac{35}{9 \div 9} \times \frac{9 \div 9}{8} - \frac{18}{8} \\ \frac{35}{1} \times \frac{1}{8} - \frac{18}{8} \\ \frac{35}{8} - \frac{18}{8} = \frac{35 - 18}{8} = \frac{17}{8}$
