Ta có 17x(1313/5151+1111/3434):177/12

         =17x(13/51+11/34):59/4

         =17x(26/102+33/102)x4/59

         =17x59/102x4/59

         =59/6x4/59

         =4/6

         =2/3

k cho mình nha

\(17\times\left(\frac{1313}{5151}+\frac{1111}{3434}\right)\div\frac{177}{12}\)

\(=17\times\left(\frac{13}{51}+\frac{11}{34}\right)\div\frac{177}{12}\)

\(=17\times\frac{59}{102}\div\frac{177}{12}\)

\(=\frac{59}{6}\div\frac{177}{12}\)

\(=\frac{59}{6}\times\frac{12}{177}\)

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

17x(13/51+11/34):177/12

=17x59/102:177/12

=59/6:177/12

=2/3

\(A=17\cdot\left(\frac{1313}{5151}+\frac{1111}{3434}\right)\div\frac{177}{12}\)

\(A=17\cdot\frac{59}{102}\div\frac{177}{12}\)

\(A=\frac{59}{6}\div\frac{177}{12}\)

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

\(a=17.\left(\frac{1313}{5151}+\frac{1111}{3434}\right):\frac{177}{12}\)
\(a=17.\left(\frac{13}{51}+\frac{11}{34}\right):\frac{177}{12}\)
\(a=17.\frac{59}{102}:\frac{177}{12}\)
\(a=\frac{59}{6}:\frac{59}{4}\)
\(a=\frac{2}{3}\)
thấy dúng thì k mik nha!!
 

= 2/3

k cho minh nha

chuc ban hoc gioi

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