Answer 1

a) \(\dfrac{3737}{5353}=\dfrac{37}{53}\); \(\dfrac{373737}{535353}=\dfrac{37}{53}\)

\(\Rightarrow\dfrac{37}{53}=\dfrac{3737}{5353}=\dfrac{373737}{535353}\)

b) \(\dfrac{39+13}{84+57}=\dfrac{52}{141}\); \(\dfrac{78+26}{168+114}=\dfrac{104}{282}=\dfrac{52}{141}\)

\(\Rightarrow\dfrac{39+13}{84+57}=\dfrac{78+26}{168+114}\)

Answer 2

Bài 1: 

a) \(\dfrac{37}{53}=\dfrac{37\cdot101}{53\cdot101}=\dfrac{3737}{5353}=\dfrac{37\cdot10101}{53\cdot10101}=\dfrac{373737}{535353}\)

b) \(\dfrac{39+13}{84+57}=\dfrac{52}{141}=\dfrac{104}{282}=\dfrac{78+26}{168+114}\)
