Question

2/3*x+x=125% x=?

 

 

Answer 1

2/3*x+x=125%

x(2/3+1)=125%

x*5/3=125%

đổi 125%=125/100=5/4

=>x*5/3=5/4

x=5/4:5/3

x=3/4

vậy x=3/4

Answer 2

\(\dfrac{2}{3}.x+x=125\%\) 

\(x.\left(\dfrac{2}{3}+1\right)=\dfrac{5}{4}\) 

        \(x.\dfrac{5}{3}=\dfrac{5}{4}\) 

             \(x=\dfrac{5}{4}:\dfrac{5}{3}\) 

             \(x=\dfrac{3}{4}\)
