Question

tìm x biết 3/5-1/4:x=25/100

Answer 1

\(\frac{3}{5}-\frac{1}{4}:x=\frac{25}{100}\)

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

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

\(\frac{1}{4}:x=\frac{7}{20}\)

\(x=\frac{1}{4}:\frac{7}{20}\)

\(x=\frac{5}{7}\)

Answer 2

\(x=\frac{5}{7}\)

Answer 3

3/5-1/4:x =1/4

1/4:x=3/5-14

        =7/20

      x=1/4:7/20

       x=5/7
