Question

5/9x4/7+5/9x3/7

Answer 1

\(\frac{5}{9}x\frac{4}{7}+\frac{5}{9}x\frac{3}{7}\)

\(=\frac{5}{9}x\left(\frac{4}{7}+\frac{3}{7}\right)\)

\(=\frac{5}{9}x1\)

\(=\frac{5}{9}\)

Answer 2

\(\frac{5}{9}\) x \(\frac{4}{7}\)+ \(\frac{5}{9}\)+ \(\frac{3}{7}\)

= \(\frac{5}{9}\)x ( \(\frac{4}{7}\)+ \(\frac{3}{7}\))

= \(\frac{5}{9}\) x 1 

= \(\frac{5}{9}\)

Answer 3

5/9*4/7+5/9*3/7

=20/63+5/21

=5/9.

Answer 4

= 5/9 nhé 

tk mình đi

và kb nữa nhá

Answer 5

5 / 9 * 4 / 7 + 5 / 9 * 3 / 7 ta sẽ làm thế này:

= ( 5 / 9 * 4 / 7 ) + ( 5 / 9 * 3 / 7 )

= 0,317 + 0,237

= 0,554

Answer 6

\(\frac{5}{9}x\frac{4}{7}+\frac{5}{9}x\frac{3}{7}=\frac{5}{9}x\left(\frac{4}{7}+\frac{3}{7}\right)=\frac{5}{9}x1=\frac{5}{9}\)
