2/21 × -3/13 +-7/9 - 2/21 × 10/13​
Viefleur [7K]

Answer:

\frac{-55}{63}

Step-by-step explanation:

=\frac{2}{21}(\frac{-3}{13})-\frac{7}{9}-\frac{2}{21}(\frac{10}{13})

=\frac{-2}{91}-\frac{7}{9}-\frac{2}{21}(\frac{10}{13})

=\frac{-2}{91} +\frac{7}{9} -\frac{2}{21} (\frac{10}{13})

=\frac{-655}{819}-\frac{2}{21} (\frac{10}{13} )

=\frac{-655}{819}-\frac{20}{273}

=\frac{-55}{63}
