Question

tìm x biết 

a)3/5:x=3

b)x:52=113

Answer 1

\(a,x=\dfrac{3}{5}:3\\ x=\dfrac{3}{5}.\dfrac{1}{3}\\ x=\dfrac{3}{15}\\ x=\dfrac{1}{5}\\ b,x=113.52\\ x=5876\)

Answer 2

\(\dfrac{3}{5}:x=3\)

\(x=\dfrac{3}{5}:3\)

\(x=\dfrac{3}{5}\times\dfrac{1}{3}\)

\(x=\dfrac{3}{15}=\dfrac{1}{5}\)

 

\(x:52=113\)

\(x=113\times52\)

\(x=5876\)
