Question

2,2+( - 6 1/3) +(- 3 1/6)

Answer 1

$2.2 + ( - 6 \frac{1}{3} ) + ( - 3 \frac{1}{6} ) = \frac{22}{10} - \frac{19}{3} - \frac{19}{6} = \frac{22 \times 3 - 19 \times 10 - 19 \times 5}{30} = \frac{66 - 190 - 95}{30} = - \frac{219}{30} = - \frac{219 \div 3}{10 \div 3} = - \frac{73}{10} = - 7 \frac{3}{10} = - 7.3$
