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.

Answer 3

To solve this expression, follow the order of operations (parentheses, exponents, multiplication and division - from left to right, and addition and subtraction - from left to right):

$\frac{8}{13} \times \left(-\frac{3}{5}\right) + \left(-\frac{3}{5}\right) \times \frac{5}{13}$

$= -\frac{24}{65} - \frac{15}{65}$

$= -\frac{39}{65}$

$= -\frac{3}{5}$
