\(\dfrac{41}{36}:\dfrac{5}{12}=\dfrac{41}{36}\times\dfrac{12}{5}=\dfrac{492}{180}=\dfrac{41}{15}\\ 8:\dfrac{16}{17}=\dfrac{8}{1}\times\dfrac{17}{16}=\dfrac{136}{16}=\dfrac{17}{2}\\ \dfrac{16}{13}:8=\dfrac{16}{13}\times\dfrac{1}{8}=\dfrac{2}{13}\)
\(\)\(\dfrac{41}{36}\) : \(\dfrac{5}{12}\) = \(\dfrac{41}{36}\) x \(\dfrac{12}{5}\) =\(\dfrac{41}{15}\)
8 : \(\dfrac{16}{17}\) = 8 x \(\dfrac{17}{16}\) =\(\dfrac{17}{2}\)

Cách 1:
( 7,54 + 2,46 ) x ( 52,96 - 52,96 )
= ( 7,54 + 2,46 ) x 0
= 0
Cách 2 : ( cách này mứt thời gian lắm )
( 7,54 + 2,46 ) x ( 52,96 - 52,96 )
= 10 x 0
= 0
Đ/S bằng 0 nha bạn

\(=\dfrac{28}{32}-\dfrac{14}{32}-\dfrac{11}{32}=\dfrac{3}{32}\)

\(=\frac{\left(\frac{9}{5}+\frac{8}{5}\right)}{\frac{17}{15}}=\frac{\left(\frac{17}{5}\right)}{\left(\frac{17}{15}\right)}=\frac{255}{85}\)

X : 15/57 + X = 3/8
X x 57/15 + X = 3/8
X x ( 57/15 + 1 ) = 3/8
X x 24/5 = 3/8
X = 3/8 : 24/5
X = 5/64
