Question

Answer 1

\(a,\dfrac{37}{53}=\dfrac{3737}{5353}=\dfrac{373737}{535353}\\ =>\dfrac{37}{53}=\dfrac{37\text{×}101}{53\text{×}101}=\dfrac{3737}{5353}\\ =>\dfrac{3737}{5353}=\dfrac{3737\text{×}101}{5353\text{×}101}=\dfrac{373737}{535353}\\ b,\dfrac{1}{3}=\dfrac{34000-68}{102000-204}\)

\(=>\)\(\dfrac{1}{3}\) và \(\dfrac{34000-68}{102000-204}\) 

\(=>\dfrac{1}{3}\) và \(\dfrac{33932}{101796}\) 

\(=>\dfrac{33932:33932}{101796:33932}=\dfrac{1}{3}\)
