Question

3/5+4/9 :x=2/3

 

Answer 1

\(\frac{3}{5}+\frac{4}{9}:x=\frac{2}{3}\)

\(\Rightarrow\frac{4}{9}:x=\frac{2}{3}-\frac{3}{5}\)

\(\Rightarrow\frac{4}{9}:x=\frac{1}{15}\)

\(\Rightarrow x=\frac{4}{9}:\frac{1}{15}\)

\(\Rightarrow x=\frac{4}{9}.\frac{15}{1}\)

\(\Rightarrow x=\frac{20}{3}\)

Answer 2

4/9:x=2/3-3/5

4/9:x=1/15

x=4/9:1/15

x=20/3

Answer 3

9^5=59049

27^3=19683

vậy 9^5>27^3

Answer 4

\(\frac{3}{5}+\frac{4}{9}:x=\frac{2}{3}\)

\(=>\frac{4}{9}:x=\frac{1}{15}\)

\(=>x=\frac{20}{3}\)

Vậy nghiệm PT trên là : \(\frac{20}{3}\)
