Question

9/4multiply by(1/2-2/9)divide13/21multiply by(-260)​

Answer 1

$\frac{ \frac{9}{4}( \frac{1}{2} - \frac{2}{9} )}{ \frac{13}{21}( - 260) } \\ \\ \\ \frac{ \frac{9}{4}( \frac{18 - 4}{18} ) }{ \frac{ - 3380}{21} } \\ \\ \\ \frac{ \frac{9}{4}( \frac{14}{18} ) }{ \frac{ - 3380}{21} } \\ \\ \\ \frac{ \frac{7}{4} }{ \frac{ - 3380}{21} } \\ \\ \frac{21 \times 7}{4 \times - 3380} = \frac{ - 147}{13520}$
