\[1)\ 40 - (2,0592\ :0,072 - 19,63) =\]

\[= 31,03\]

\[2,0592\ :0,072 = 20\ 592\ :720 =\]

\[28,6 - 19,63 = 8,97\]

\[40 - 8,97 = 31,03\]

\[7,67\ :0,65 = 767\ :65 = 11,8\]

\[1,1628\ :0,57 =\]

\[= 11\ 628\ :5700 = 2,04\]

\[39 - 6,96 = 32,04\]

\[38,4\ :16 = 384\ :160 = 2,4\]

\[42,4 - 2,4 = 40\]
