x = 4/5 : 3/4
x = 16/15
x = 5/9 : 8/3
x = 5/9 x 3/8
x = 5/24
\(x=\dfrac{4}{5}\times\dfrac{4}{3}\)
\(x=\dfrac{16}{15}\)
-----------------------
\(x=\dfrac{5}{9}\times\dfrac{3}{8}\)
\(x=\dfrac{5}{24}\)
\(x\times\dfrac{3}{4}=\dfrac{4}{5}\)
\(x=\dfrac{4}{5}:\dfrac{3}{4}\)
\(x=\dfrac{4}{5}\times\dfrac{4}{3}\)
\(x=\dfrac{16}{15}\)
\(\dfrac{5}{9}:x=\dfrac{8}{3}\)
\(x=\dfrac{5}{9}:\dfrac{8}{3}\)
\(x=\dfrac{5}{9}\times\dfrac{3}{8}\)
\(x=\dfrac{15}{72}\)
\(x=\dfrac{5}{24}\)
x = 4/5 : 3/4
x = 16/15
vậy x = ...
x = 5/9 : 8/3
x = 5/24
vậy x = ...
