Question

(​​\(\frac{3}{4}\)  * x -  0,54   ) : \(\frac{2}{9}\)=\(\frac{3}{4}\)- 0,48

tỉm x

Answer 1

\(\left(\frac{3}{4}\times x-0,54\right):\frac{2}{9}=\frac{3}{4}-0,48\)

\(\left(\frac{3}{4}\times x-0,54\right):\frac{2}{9}=0,27\)

       \(\left(\frac{3}{4}\times x-0,54\right)=0,27\times\frac{2}{9}\)

         \(\left(\frac{3}{4}\times x-0,54\right)=0,06\)

                              \(\frac{3}{4}\times x=0,06+0,54\)

                                \(\frac{3}{4}\times x=0,6\)

                                            \(x=0,6:\frac{3}{4}\)

                                             \(x=0,8\)

Answer 2

​(3/4 *x -0.54):2/9 = 3/4- 12/25

(3/4 *x- 27/50) :2/9 =27/100

3/4*x- 27/50 = 27/100* 2/9

3/4*x-27/50 = 3/50

3/4*x = 3/50+ 27/50

3/4*x =3/5

x= 3/5:3/4= 4/5
