Question

7/9 nhân 3/5 trừ x =1/4

Answer 1

\(\frac{7}{9}\cdot\frac{3}{5}-x=\frac{1}{4}\)

\(=\frac{7}{15}-x=\frac{1}{4}\)

\(x=\frac{7}{15}-\frac{1}{4}\)

\(x=\frac{13}{60}\)

Answer 2

7/9 * 3/5 -x = 1/4

7/15 - x  = 1/4

x = 13/60

Answer 3

7/9 x 3/5 - x = 1/4

         3/5 - x = 1/4 : 7/9

         3/5 - x = 9/28

                  x =  3/5 - 9/28

                 x = 39/140
