17 x ( 1313/5151 + 1111/3434) : 177/12
= 17 x ( 13/51 + 11/34 ) : 59/4
= 17 x 59/102 : 59/4
= (17 x 59/102) : 59/4
= 59/6 : 59/4

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
\(17\times\left(\frac{1313}{5151}+\frac{1111}{3434}\right)\div\frac{177}{12}\)
\(=17\times\left(\frac{13}{51}+\frac{11}{34}\right)\div\frac{177}{12}\)
\(=17\times\frac{59}{102}\div\frac{177}{12}\)
\(=\frac{59}{6}\div\frac{177}{12}\)
\(=\frac{59}{6}\times\frac{12}{177}\)
\(=\frac{2}{3}\)
