\(2018\times(\frac{1}{2}+\frac{1212}{2424}\))

Answer 1

\(2018\times\left(\frac{1}{2}+\frac{1212}{2424}\right)=2018\times\left(\frac{1}{2}+\frac{12}{24}\right).\)

                                                  \(=2018\times\left(\frac{1}{2}+\frac{1}{2}\right)\)

                                                  \(=2018\times1=2018\)

Answer 2

2018.(1/2+1212/2424)

=2018.(1/2+1/2)

=2018.2/2

=2018.1

=2018
