Question

         Tìm x

   x-25%x=0,5

      nhanh lên nhé mình sắp phải nộp bài rồi !!!

Answer 1

x - 25%x = 0,5

=> x - 1/4.x = 1/2

=> 3/4.x = 1/2

=> x = 1/2 : 3/4

=> x = 2/3

Answer 2

x-25%.x= 0,5

x.1-\(\frac{1}{4}\).x= \(\frac{1}{2}\)

x.(1-\(\frac{1}{4}\))= \(\frac{1}{2}\)

x.\(\frac{3}{4}\)=\(\frac{1}{2}\)

x    =\(\frac{1}{2}:\frac{3}{4}\)

x     =\(\frac{2}{3}\)

Answer 3

Chúc làm bài tốt

Answer 4

\(x-25\%x=0,5\)

\(x-\frac{1}{4}x=\frac{1}{2}\)

\(x.\left(1-\frac{1}{4}\right)=\frac{1}{2}\)

\(x.\frac{3}{4}=\frac{1}{2}\)

\(x=\frac{1}{2}:\frac{3}{4}=\frac{2}{3}\)

Answer 5

\(x-25\%x=0,5\)

\(x-\frac{1}{4}x=\frac{1}{2}\)

\(x.1-x.\frac{1}{4}=\frac{1}{2}\)

\(x.\frac{3}{4}=\frac{1}{2}\)

\(x=\frac{2}{3}\)
