Answer 2

\(1,25x=25\%\)

\(1,25x=0,25\)

\(x=0,25:1.25\)

\(x=0,2\)

Answer 3

\(x=\dfrac{25}{100}:\dfrac{5}{4}\)

\(x=\dfrac{25}{100}\times\dfrac{4}{5}\)

\(x=\dfrac{1}{4}\times\dfrac{4}{5}\)

\(x=\dfrac{4}{20}\)

\(x=\dfrac{1}{5}\)

Answer 4

1,25x=25%

x=25/100:125/100

vậy x = 1/5 ( đả rút gọn)
