a) \(x=\dfrac{12}{11}:\dfrac{6}{13}\)
\(x=\dfrac{26}{11}\)
b) \(x:\dfrac{5}{7}=\dfrac{4}{5}\)
\(x=\dfrac{4}{5}x\dfrac{5}{7}\)
\(x=\dfrac{4}{7}\)
a, x = 12/11 : 6/13
x = 26/11
vậy x =...
b) x : 5/7 = 4/5
x = 4/5 x 5/7
x = 4/7
vậy x = ...
a, x = 12/11 : 6/13
x = 26/11
b) x : 5/7 = 4/5
x = 4/5 x 5/7
x = 4/7
