Question

($frac{1}{3}$ + $0,75$) : ($frac{2}{3}$ - $frac{5}{12}$) =

Answer 1

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

Answer 2

( 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
