1) -48

2) 56

3) 3.22

4) -24/49

5) -4/9

6) 1,25 (5/4)

7) 18

8) 32/7 (4целых 4/7)

Answer 2

$\displaystyle \tt 1) \: 16\cdot (-3)=-48\\\displaystyle \tt 2) \: -8\cdot (-7)=56\\\displaystyle \tt 3) \: -2,3\cdot(-1,4)=3,22\\\displaystyle \tt 4) \:\frac{6}{7}\cdot (-\frac{4}{7})=-\frac{24}{49}\\\displaystyle \tt 5) \: -\frac{4}{7}\cdot \frac{7}{9}=-\frac{4}{9}\\\displaystyle \tt 6) \: -6\cdot (-\frac{5}{24})=\frac{5}{4}=1,25\\\displaystyle \tt 7) \: -\frac{6}{19}\cdot (-57)=6\cdot3=18$

$\displaystyle \tt 8) \: -9\frac{3}{5}\cdot (-\frac{10}{21})=-\frac{48}{5}\cdot (-\frac{10}{21})=16\cdot \frac{2}{7}=\frac{32}{7}=4\frac{4}{7}$
