Ta có: \(13\cdot\left(-47\right)-53\cdot13\)
\(=13\cdot\left(-47-53\right)\)
\(=13\cdot\left(-100\right)=-1300\)
Ta có: \(27\cdot\left(-67\right)+33\cdot\left(-27\right)\)
\(=27\cdot\left(-67\right)-33\cdot27\)
\(=27\left(-67-33\right)\)
\(=27\cdot\left(-100\right)=-2700\)
Ta có: \(-49\cdot65+36\cdot\left(-49\right)+49\)
\(=-49\cdot65+\left(-49\right)\cdot36+\left(-49\right)\cdot\left(-1\right)\)
\(=-49\cdot\left(65+36-1\right)\)
\(=-49\cdot100=-4900\)
Ta có: \(136\cdot\left(-47\right)+36\cdot47\)
\(=\left(-136\right)\cdot47+36\cdot47\)
\(=47\cdot\left(-136+36\right)\)
\(=47\cdot\left(-100\right)=-4700\)
Ta có: \(\left(-48\right)\cdot72+36\cdot\left(-304\right)\)
\(=-96\cdot36+36\cdot\left(-304\right)\)
\(=36\cdot\left(-96-304\right)\)
\(=36\cdot\left(-400\right)=-14400\)

\(\dfrac{3}{41}-\dfrac{12}{47}+\dfrac{27}{53}+\dfrac{4}{41}-\dfrac{16}{47}+\dfrac{36}{53}\)
\(=\left(\dfrac{3}{41}+\dfrac{4}{41}\right)-\left(\dfrac{12}{47}+\dfrac{16}{47}\right)+\left(\dfrac{27}{53}+\dfrac{36}{53}\right)\)
\(=\dfrac{7}{41}-\dfrac{28}{47}+\dfrac{63}{53}\)
\(=-\dfrac{819}{1927}+\dfrac{63}{53}\)
≃\(0,8\)
a) 36 + 53 + 47 + 64 = (36+64)+(53+47)= 100+100=200
b) =(242-42)+(167-67)= 200+100=300
