\(\frac{54.107-53}{53.107-54}=\frac{\left(53+1\right).107-53}{53.107-54}=\frac{53.107+107-53}{53.107-54}=\frac{53.107+54}{53.107-54}=1-1=0\)
why? why? why?....
\(\frac{53\cdot107+54}{53\cdot107-54}=1-1\)
Ta có: \(\frac{54.107-53}{53.107-54}=\frac{\left(53+1\right)107-53}{53.107-54}=\frac{53.107+107-53}{53.107-54}=\frac{53.107+54}{53.107-54}\)
