Question

Tìm số tự nhiên x sao cho:nhanh thì tick

\(\frac{x}{5}x\frac{5}{6}x9=\frac{4x5x6}{5x6}\)

Answer 1

\(\frac{x}{5}x\frac{5}{6}x9=\frac{4x5x6}{5x6}\)

\(\frac{x}{6}x9=4\)

\(\frac{x}{6}=\frac{4}{9}\)

\(x=4x6:9=\frac{8}{3}\)

học tốt ~~~

Answer 2

x/5 x 5/6 x 9 = 120/30 = 4

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

x/5 = 4/9 : 5/6 = 8/15

=> x/5 = 8/15 => x = 8/3 chắc chắn 

Answer 3

x = 8/3
