Tinh bang cach hop li : 

37/53+23/48+535353/373737+242424/232323

Answer 1

=\(\frac{37}{53}+\frac{23}{48}+\frac{53}{37}+\frac{24}{23}\)

=\(\left(\frac{37}{53}+\frac{53}{37}\right)+\left(\frac{23}{24.2}+\frac{24}{23}\right)\)

=\(1+\left(\frac{23}{24}-\frac{23}{2}+\frac{23}{24}\right)\)

=\(1+\frac{23}{2}=\frac{25}{2}\)
