-3/11:(1 5/22)
/ это дробь

Answer 1

$1) 3 \frac{7 {}^{(25} }{4} \times ( - 1.4) = 3 + \frac{175}{100} \times ( - 1.4) = 3 + 1 \frac{75}{100} \times ( - 1.4) = 4.75 \times ( - 1.4) = - 6.65 = - 6 \frac{65}{100}$

$2)- \frac{3}{11} \div (1 \frac{5}{22} ) = - \frac{3}{11} \div 1 \frac{5}{22} = - \frac{3}{11} \div \frac{27}{22} = - \frac{3}{11} \times \frac{22}{27} = - \frac{3 \times 22}{11 \times 27} = - \frac{66}{297} = - \frac{2}{9}$
