Question

Giúp mik giải rõ ràng nhé

Answer 1

a) \(x=\dfrac{12}{11}:\dfrac{6}{13}\)

\(x=\dfrac{26}{11}\)

b) \(x:\dfrac{5}{7}=\dfrac{4}{5}\)

\(x=\dfrac{4}{5}x\dfrac{5}{7}\)

\(x=\dfrac{4}{7}\)

Answer 2

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 = ...

Answer 3

a, x = 12/11 : 6/13

x = 26/11

b) x : 5/7 = 4/5

x = 4/5 x 5/7

x = 4/7
