=1/2
\(\dfrac{16}{24}-\dfrac{1}{6}\\ =\dfrac{16:8}{24:8}-\dfrac{1}{6}\\ =\dfrac{2}{3}-\dfrac{1}{6}\\ =\dfrac{2\times2-1}{6}=\dfrac{3}{6}=\dfrac{1}{2}\)
\(\dfrac{16}{24}-\dfrac{1}{6}=\dfrac{16}{24}-\dfrac{1\cdot4}{6\cdot4}=\dfrac{16}{24}-\dfrac{4}{24}=\dfrac{12}{24}=\dfrac{1}{2}\)rút gọn đc \(\dfrac{1}{2}\)
\(\dfrac{16}{24}\) - \(\dfrac{1}{6}\)= \(\dfrac{16}{24}\) - \(\dfrac{4}{24}\) = \(\dfrac{12}{24}\) = \(\dfrac{1}{2}\)
