\(\frac{3}{5}-\frac{1}{4}\div x=\frac{25}{100}\)
\(\frac{3}{5}-\frac{1}{4}\div x=\frac{1}{4}\)
\(\frac{1}{4}\div x=\frac{3}{5}-\frac{1}{4}\)
\(\frac{1}{4}\div x=\frac{7}{20}\)
\(x=\frac{1}{4}\div\frac{7}{20}\)
\(x=\frac{5}{7}\)
Ta có: 3/5 - 1/4 : x = 25/100
=> 1/4 : x = 3/5 - 25/100
=> 1/4 : x = 7/20
=> x = 1/4 : 7/20
=> x = 5/7
Vậy x = 5/7
\(\frac{3}{5}\)- \(\frac{1}{4}\): 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 = \(\frac{1}{4}\)x \(\frac{20}{7}\)
x = \(\frac{5}{7}\)
