/=supra

Answer 1

( 1/36 - 2/24 ) : 1/48 =
( 1/36 - 1/12 ) : 1/48 =
$\frac{1-3}{36}$ : 1/48 =
( - 2/36 ) : 1/48 =
- 1/18 ori 48 =
- 1/3 ori 8 =
- 8/3

Bafta :)

Answer 2

$\Big(\dfrac{1}{36}- \dfrac{2}{24}\Big): \dfrac{1}{48} =\Big(\dfrac{1}{36}- \dfrac{1}{12}\Big): \dfrac{1}{48} = \Big(\dfrac{1}{36}- \dfrac{3}{36}\Big): \dfrac{1}{48}= \\ \\ = \dfrac{1-3}{36} : \dfrac{1}{48} = \dfrac{-2}{36} : \dfrac{1}{48} = \dfrac{-2}{36} \cdot \dfrac{48}{1} = \dfrac{-2\cdot 48}{36} = \dfrac{-48^{ \backslash 2}}{18} = -\dfrac{24^{\backslash 3}}{9} = -\dfrac{8}{3}$
