Question

\(\frac{a}{6}\) x \(\frac{8}{11}\) = \(\frac{2}{3}\)

Answer 1

\(\frac{a}{6}=\frac{2}{3}:\frac{8}{11}\)

\(\frac{a}{6}=\frac{11}{12}\)

\(\frac{2a}{12}=\frac{11}{12}\)

2a=11

Vậy a ko tồn tại  

Answer 2

\(\frac{a}{6}\times\frac{8}{11}=\frac{2}{3}\)

\(\frac{a}{6}=\frac{2}{3}:\frac{8}{11}\)

\(\frac{a}{6}=\frac{11}{12}\)

=> Không có a

Answer 3

\(\frac{2}{3}\div\frac{8}{11}=\frac{2}{3}\times\frac{11}{8}=\frac{22}{24}=\frac{11}{12}\)

Answer 4

= 11/12

Answer 5

11/12
