                                               =

                                               = ?   

ai đúng sẽ kick cho người đó ^^

Answer 1

\(2\frac{3}{13}.\frac{27}{58}.2\frac{15}{24}.\frac{8}{21}:\frac{3}{7}=\frac{29}{13}.\frac{27}{58}.\frac{63}{24}.\frac{8}{21}:\frac{3}{7}=\frac{27}{26}.\frac{63}{24}.\frac{8}{21}:\frac{3}{7}=\frac{567}{208}.\frac{8}{21}:\frac{3}{7}=\frac{27}{26}:\frac{3}{7}=\frac{63}{26}\)

Answer 2

Answer 3

2 3/13x27/58x2 15/24x8/21:3/7

=(2 3/13x27/58)x(2 15/24x8/21):3/7

=27/26x1:3/7

=27/26:3/7

=63/26=2 11/26
