Question

4/5 x 3/7 +4/5 x 6/7 - 4/5 x 4/14

Answer 1

=4/5(3/7+6/7-2/7)=4/5

Answer 2

4/5.(3/7+6/7-4/14)

=4/5.1

=4/5

Answer 3

4/5

Answer 4

=4/5 x (3/7+6/7-4/14)

=4/5x1=4/5

Answer 5

\(=\dfrac{4}{5}\times\left(\dfrac{3}{7}+\dfrac{6}{7}-\dfrac{4}{14}\right)=\dfrac{4}{5}\times\left(\dfrac{9}{7}-\dfrac{2}{7}\right)=\dfrac{4}{5}\times1=\dfrac{4}{5}\)

Answer 6

\(\dfrac{4}{5}\times\dfrac{3}{7}+\dfrac{4}{5}\times\dfrac{6}{7}-\dfrac{4}{5}\times\dfrac{4}{14}=\dfrac{4}{5}\times\left(\dfrac{3}{7}+\dfrac{6}{7}-\dfrac{4}{14}\right)=\dfrac{4}{5}\times\dfrac{7}{7}=\dfrac{4}{5}\times1=\dfrac{4}{5}\)

Answer 7

\(\dfrac{4}{5}\times\dfrac{3}{7}+\dfrac{4}{5}\times\dfrac{6}{7}-\dfrac{4}{5}\times\dfrac{4}{14}\)

\(=\dfrac{4}{5}\times\left(\dfrac{3}{7}+\dfrac{6}{7}-\dfrac{4}{14}\right)\)

\(=\dfrac{4}{5}\times1\)

\(=\dfrac{4}{5}\)
