\(\dfrac{112}{15}:x=\dfrac{28}{3}\\ =>x=\dfrac{112}{15}:\dfrac{28}{3}\\ =>x=\dfrac{112}{15}\times\dfrac{3}{28}\\ =>x=\dfrac{4}{5}\)
\(< =>x=\dfrac{112}{15}:\dfrac{28}{3}< =>x=\dfrac{4}{5}\)
\(\dfrac{112}{15}:x=\dfrac{28}{3}\)
\(x=\dfrac{112}{15}:\dfrac{28}{3}\)
\(x=\dfrac{112}{15}.\dfrac{3}{28}\)
\(x=\dfrac{336}{420}\)
\(x=\dfrac{112}{15}:\dfrac{28}{3}\)
\(x=\dfrac{112}{15}\times\dfrac{3}{28}\)
\(x=\dfrac{4}{5}\)
\(\dfrac{112}{15}:x=\dfrac{28}{3}\)
\(x=\dfrac{112}{15}:\dfrac{28}{3}\)
\(x=\dfrac{122}{15}\times\dfrac{3}{28}\)
Vậy \(x=\dfrac{4}{5}\)
