Question

СРОЧНОО
1) -6,2 * 3,4
2)-6 3/4 * (1 11/45)
3)-19,68 : (-0,8)
4) 16,32 : (-16)

Answer 1

$- 6.2 \times 3.4 = - 21.08$

$- 6 \frac{3}{4} \times 1 \frac{11}{45} = - \frac{27 \times 56}{4 \times 45} = - \frac{3 \times 14}{1 \times 5} = - \frac{42}{5} = - 8.4$

$- 19.68 \div ( - 0.8) = 196.8 \div 8 = 24.6$

$16.32 \div ( - 16) = - 1.02$
