Question

x : 5/3 + 2/5 =9/5

giúp mình với

Answer 1

x:5/3=9/5+2/5

x:5/3=11/5

x=11/5.5/3

x=11/3

Answer 2

x : 5/3 = 9/5 - 2/5

x : 5/3 = 7/5

x = 7/5 x 5/3

x = 7/3

Answer 3

\(x:\dfrac{5}{3}+\dfrac{2}{5}=\dfrac{9}{5}\)

\(x:\dfrac{5}{3}=\dfrac{9}{5}-\dfrac{2}{5}\)

\(x:\dfrac{5}{3}=\dfrac{7}{5}\)

\(x=\dfrac{7}{5}\times\dfrac{5}{3}\)

\(x=\dfrac{35}{15}=\dfrac{7}{3}\)
