  1. 4/7+5/6 ÷5 – 0,375 × (- 2)^2
    =4/7 + 5/30 – 3/8 × 4
    =31/42 – 3/2
    =-16/21
     

  2.    $\dfrac{4}{7}$ + $\dfrac{5}{6}$ : $\text{5}$ – $\text{0,375}$ x (-$\text{-2}$$x^{2}$)
    = $\dfrac{4}{7}$ + $\dfrac{1}{6}$ – $\text{0,375}$ x 4
    = $\dfrac{4}{7}$ + $\dfrac{1}{6}$ – $\dfrac{3}{2}$
    = $\dfrac{31}{42}$ – $\dfrac{3}{2}$
    = -$\dfrac{16}{21}$
