Answer 1

Răspuns:

$\frac{1}{1} =1$

Explicație pas cu pas:

$(2+3*\frac{1}{2}):2\frac{1}{2} =\\\\(2+\frac{3}{1} *\frac{1}{2} ):\frac{2*2+1}{2} =\\\\(2+\frac{3}{2} ):\frac{5}{2}= \\\\(\frac{2}{2} +\frac{3}{2} ):\frac{5}{2} =\\\\\frac{5}{2} :\frac{5}{2} =\\\\\frac{5}{2} *\frac{2}{5} =\\\\\frac{1}{1}*\frac{1}{1}=\\\\\frac{1}{1} =1$

Succes! :)
