Question

(-3,4+7)•(-1 7/18)
(6 2/9•5 5/6):(-7/36)

Answer 1

$( - 3.4 + 7) \times ( - 1 \frac{7}{18} ) = 3.6 \times ( - \frac{25}{18} ) = \frac{18}{5} \times ( - \frac{25}{18}) = - 5$

$(6 \frac{2}{9} \times 5 \frac{5}{6} ) \div ( \frac{ - 7}{36} ) = ( \frac{56}{9} \times 5 \times \frac{5}{6} ) \div \frac{ - 7}{36} = ( \frac{28}{9} \times 5 \times \frac{5}{3} ) \div \frac{ - 7}{36} = \frac{700}{27} \div \frac{ - 7}{36} = - \frac{700}{27} \times \frac{36}{7} = - \frac{100}{3} \times 4 = - \frac{400}{3}$
