Question

\(3\frac{1}{3}.\)x -\(6\frac{1}{4}\)=\(3\frac{1}{4}\)

ai k tớ tớ tk lại

Answer 1

= \(\frac{10}{3}.x-\frac{25}{4}=\frac{13}{4}\)

    \(\frac{10}{3}.x=\frac{13}{4}+\frac{25}{4}\)\(=\frac{19}{2}\)

             \(x=\frac{19}{2}:\frac{10}{3}\)

             \(x=\frac{57}{20}\)

            k mk mk k lại n_n

Answer 2

3 1/3x=9 1/2

x=57/20

Answer 3

\(3\frac{1}{2}.x-6\frac{1}{4}=3\frac{1}{4}\)

           \(3\frac{1}{2}.x=3\frac{1}{4}+6\frac{1}{4}\)

           \(3\frac{1}{2}.x=9\frac{1}{2}\) 

                  \(x=9\frac{1}{2}:3\frac{1}{2}\)

                   \(x=\frac{19}{7}\)

Answer 4

\(x=3\)

Answer 5

\(3\frac{1}{3}x-6\frac{1}{4}=3\frac{1}{4}\\\\=>3\frac{1}{3}x=3\frac{1}{4}+6\frac{1}{4}=9\frac{1}{2}\\ =>x=9\frac{1}{2}:3\frac{1}{3}=\frac{57}{20} \)

Answer 6

k tớ tớ k lại nha

Answer 7

\(3\frac{1}{3}.x-6\frac{1}{4}=3\frac{1}{4}\)

             \(3\frac{1}{3}.x=3\frac{1}{4}+6\frac{1}{4}\)

             \(3\frac{1}{3}.x=9\frac{1}{2}\)

                    \(x=9\frac{1}{2}:3\frac{1}{3}\)

                    \(x=\frac{57}{20}\)
