Cách 2 cữa bạn ơi

Answer 3

       (\(\frac{3}{4}\)+ \(\frac{1}{2}\)) x \(\frac{5}{7}\)

= \(\frac{5}{4}\)x \(\frac{5}{7}\)

= \(\frac{25}{28}\)

Answer 4

C2

\(\left(\frac{3}{4}+\frac{1}{2}\right)\cdot\frac{5}{7}\)

=\(\frac{5}{7}\cdot\frac{3}{4}+\frac{5}{7}\cdot\frac{1}{2}\)

=\(\frac{15}{28}+\frac{5}{14}\)

=\(\frac{25}{28}\)

Answer 5

\(\left(\frac{3}{4}+\frac{1}{2}\right)X\frac{5}{7}=\frac{5}{4}X\frac{5}{7}=\frac{25}{28}\)

Answer 6

(\(\frac{3}{4}\)+ \(\frac{1}{2}\)) x \(\frac{5}{7}\)

= (\(\frac{6}{8}\)+ \(\frac{4}{8}\)) x \(\frac{5}{7}\)

=  \(\frac{10}{8}\)x \(\frac{5}{7}\)

=\(\frac{50}{56}\)

=\(\frac{25}{28}\)
