4248 : ( 2 x 9 ) = 4248 : 18 = 236

4248 : 2 : 9 = 2124 : 9 = 236

= \(\dfrac{17}{15}\)

???

có đồng nghĩa

nhầm

29752 : 8 = 3719

a) \(\dfrac{5}{4}\) x \(\dfrac{2}{3}\) + \(\dfrac{1}{6}\) = \(\dfrac{10}{12}\) + \(\dfrac{1}{6}\) = \(\dfrac{10}{12}\) + \(\dfrac{2}{12}\) = 1

b)\(\dfrac{17}{4}\) - \(\dfrac{2}{3}\) : \(\dfrac{1}{6}=\) \(\dfrac{17}{4}\) - \(\dfrac{12}{3}\) = \(\dfrac{51}{12}\) - \(\dfrac{48}{12}=\) \(\dfrac{1}{4}\)
