Question

Tính BT sau: A =\(\left(\frac{878787}{959595}+\frac{-8787}{9595}\right).\frac{1234321}{5678765}\)

Answer 1

\(A=\left(\frac{878787}{959595}+\frac{-8787}{9595}\right).\frac{1234321}{5678765}\)

\(=\left(\frac{87.10101}{95.10101}-\frac{87.101}{95.101}\right).\frac{1234321}{5678765}\)

\(=\left(\frac{87}{95}-\frac{87}{95}\right).\frac{1234321}{5678765}\)

= 0 

Answer 2

\(A=\left(\frac{87}{95}+\frac{-87}{95}\right).\frac{1234321}{5678765}\)

=>\(A=0.\frac{1234321}{5678765}\)

=>A=0
