Question

(\(\frac{1313}{1414}\)+\(\frac{10}{160}\))-(\(\frac{130}{140}\)-\(\frac{1515}{1616}\))

Answer 1

\(\left(\frac{1313}{1414}+\frac{10}{160}\right)-\left(\frac{130}{140}-\frac{1515}{1616}\right)\)

\(=\left(\frac{13}{14}+\frac{1}{16}\right)-\left(\frac{13}{14}-\frac{15}{16}\right)\)

\(=\frac{13}{14}+\frac{1}{16}-\frac{13}{14}+\frac{15}{16}\)

\(=\left(\frac{13}{14}-\frac{13}{14}\right)+\left(\frac{1}{16}+\frac{15}{16}\right)\)

\(=0+1\)

\(=1\)

Answer 2

Có (\(\frac{1313}{1414}\)+\(\frac{10}{160}\)) - (\(\frac{130}{140}\)-\(\frac{1515}{1616}\))

=\(\frac{13}{14}\)+\(\frac{1}{16}\)-\(\frac{13}{14}\)+\(\frac{15}{16}\)

=(\(\frac{13}{14}-\frac{13}{14}\)) + (\(\frac{1}{16}+\frac{15}{16}\))

=0+1=1
