Question

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

Answer 1

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

\(=\frac{8}{35}+\frac{4}{15}\)

\(=\frac{52}{105}\)

\(K\)\(nha!!\)

Answer 2

4/5.2/7+1/3.4/5

=4/5.(2/7+1/3)

=4/5.13/21

=149/105

Answer 3

\(\frac{4}{5}x\frac{2}{7}+\frac{1}{3}x\frac{4}{5}\)\(=\frac{4}{5}x\left(\frac{2}{7}+\frac{1}{3}\right)=\frac{4}{5}x\frac{13}{21}\)\(=\frac{52}{105}\)

chúc bn học giỏi

Answer 4

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

\(=\frac{8}{35}\cdot\frac{4}{15}\)

\(=\frac{35}{525}\)

Answer 5

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

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

\(=\frac{4}{5}\times\frac{13}{21}\)

\(=\frac{52}{105}\)

tíc mình nha

Answer 6

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

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

\(=\frac{4}{5}\times\frac{13}{21}\)

\(=\frac{52}{105}\)

Answer 7

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

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

\(=\frac{4}{5}\times\frac{13}{21}\)

\(=\frac{52}{105}\)
