Question

Tìm x :

\(\dfrac{8}{9}\) x \(\dfrac{3}{6}\) : x = \(\dfrac{5}{4}\)

 

Answer 1

`8/9xx3/6:x=5/4`

`4/9:x=5/4`

`x=4/9:5/4`

`x=4/9xx4/5=16/45`

Answer 2

\(\dfrac{4}{9}\):x=\(\dfrac{5}{4}\)

x=\(\dfrac{4}{9}\):\(\dfrac{5}{4}\)=\(\dfrac{16}{45}\)

Answer 3

8/9.3/6:x=5/4

3/6:x=5/4:8/9

3/6:x=45/32

x=3/6:45/32

x=16/45

Answer 4

Answer 5

\(\dfrac{8}{9}\times\dfrac{3}{6}:x=\dfrac{5}{4}\)

\(\dfrac{3}{6}:x=\dfrac{5}{4}:\dfrac{8}{9}\)

\(\dfrac{3}{6}:x=\dfrac{5}{4}\times\dfrac{9}{8}\)

\(\dfrac{3}{6}:x=\dfrac{45}{32}\)

\(x=\dfrac{3}{6}:\dfrac{45}{32}\)

\(x=\dfrac{16}{45}\)
