Question

(—3,4)•(1–1 10/17•(-4/7))

Answer 1

$( - 3.4) \times (1 - 1 \frac{10}{17} \times ( - \frac{4}{7} )) = ( - 3.4) \times (1 + \frac{27 \times 4}{17 \times 7} ) = ( - 3.4) \times (1 + \frac{108}{119} ) = (- 3.4) \times 1 \frac{108}{119} = - \frac{17 \times 227}{5 \times 119} = - \frac{227}{5 \times 7} = - \frac{227}{35} = - 6 \frac{17}{35}$
