( 1/3+0,75) : ( 2/3-5/12 ) =((1·4)/(4·3)+3·3/(3·4)): ( (2·4)/12-5/12 ) = =(4+9)/12: ( (8-5)/12 ) =(13/12)·12/3=13/3=4+1/3

Accepted Answer

[latex] (\frac{1}{3} +0,75):( \frac{2}{3} -\frac{5}{12} )=(\frac{1}{3} +\frac{3}{4} ):(\frac{8}{12} -\frac{5}{12} )=(\frac{4}{12} +\frac{9}{12} ): \frac{3}{12} = \frac{13}{12} :\frac{3}{12}= \\ = \frac{13}{3} =4 \frac{1}{3} [/latex]
