M.n giải giùm mk vs. Mk giải hk ra

Answer 1

\(\frac{3}{7}:x+\frac{1}{4}=\frac{5}{9}\)

\(\frac{3}{7}:x=\frac{5}{9}-\frac{1}{4}=\frac{20-9}{36}=\frac{11}{36}\)

\(x=\frac{3}{7}:\frac{11}{36}=\frac{3}{7}\times\frac{36}{11}=\frac{3\times36}{7\times11}=\frac{108}{77}\)

Vậy \(x=\frac{108}{77}\)

Answer 2

\(\frac{3}{7}:x+\frac{1}{4}=\frac{5}{9}\)

\(\frac{3}{7}:x=\frac{5}{9}-\frac{1}{4}\)

\(\frac{3}{7}:x=\frac{11}{36}\)

\(x=\frac{3}{7}:\frac{11}{36}\)

\(x=\frac{108}{77}\)

Answer 3

3/7:x+1=5/9

3/7:x=5/9-1

3/7:x=-4/9

x=3/7:-4/9

x=âm27phần28
