58 + 92 -73:11
=58 + 92 -73/11
=150-73/11
=1577/11
25+72:(24+1)+72
=25+72:25+72
=25+2,88+72
=27,88+72
=99,88
\(=150-\frac{73}{11}=\frac{1577}{11}\)
\(=25+72:25+72=25+72:\left(25+1\right)=25+72:26=25+3=28\)
27 * 4 + 27 * 6
= 27 * ( 4 + 6 )
= 27 * 10
= 270
73 * 2 + 73 * 8
= 73 * ( 2 + 8 )
= 73 * 10
= 730
\(32\times27+47\times73+27\times15\)
\(=\left(32\times27+27\times15\right)+47\times73\)
\(=27\times\left(32+15\right)+47\times73\)
\(=27\times47+47\times73\)
\(=47\times\left(27+73\right)\)
\(=47\times100\)
\(=4700\)

\(=32\cdot27+27\cdot15+47\cdot73\)
\(=27\cdot\left(32+15\right)+47\cdot73\)
\(=27\cdot47+47\cdot73\)
\(=47\cdot\left(27+73\right)\)
\(=47\cdot100\)
\(=4700\)
\(\frac{5}{27}+\frac{3}{4}+\frac{22}{27}+\frac{1}{4}\)
\(=\left(\frac{5}{27}+\frac{22}{27}\right)+\left(\frac{3}{4}+\frac{1}{4}\right)\)
\(=1+1\)
\(=2\)
\(\frac{89}{92}-\frac{30}{92}-\frac{59}{92}\)
\(=\frac{89-30-59}{92}\)
\(=\frac{59-59}{92}\)
\(=\frac{0}{92}\)
\(=0\)
