\(\frac{11}{17}:\frac{77}{68}=\frac{11.68}{17.77}=\frac{11.17.4}{17.7.11}=\frac{4}{7}\)
11/17 : 77/68 = 11/17 x 68/77 = 11 x68/17x77 = 11x17x4/17x11x7 = 4/7
\(\frac{11}{17}:\frac{77}{68}=\frac{11}{17}.\frac{68}{77}\)= \(\frac{1.4}{1.7}=\frac{4}{7}\)
11/17:77/68=11/17x68/77=11x17x4/17x11x7(gạch các số 11;17)=4/7
