Question

8/13×(-3/5)+(-3/5)×5/13

Answer 1

$frac{8}{13} times ( - frac{3}{5} ) + ( - frac{3}{5} ) times frac{5}{13} = \ = ( - frac{3}{5} )( frac{8}{13} + frac{5}{13} ) = ( - frac{3}{5} ) times frac{13}{13} = \ = - frac{3}{5} times 1 = - frac{3}{5}$

Answer 2

8/13×(-3/5)+(-3/5)×5/13 = -24/65+(-3/13) = -24/65+(-15/65) = -24/65-15/65 = -39/65 = -3/5
Ответ: -3/5.
