Answer 1

[Nobi Nobita]

\(\frac{82}{59}+\frac{95}{91}+\frac{36}{59}+\frac{87}{91}=\left(\frac{82}{59}+\frac{36}{59}\right)+\left(\frac{95}{91}+\frac{87}{91}\right)\)

\(=\frac{118}{59}+\frac{182}{91}=2+2=4\)

Answer 2

[Hiền Thương]

\(\frac{82}{59}+\frac{95}{91}+\frac{36}{59}+\frac{87}{91}\) \(=\left(\frac{82}{59}+\frac{36}{59}\right)+\left(\frac{95}{91}+\frac{87}{91}\right)=\frac{118}{59}+\frac{182}{92}=2+2=4\)
