Salutare!
[tex]\bf a = \dfrac{5}{20}:\dfrac{5}{18} \implies a = \dfrac{5}{20}\cdot\dfrac{18}{5}\implies a = \dfrac{\not5}{\not20}\cdot\dfrac{\not18}{\not5} \implies \boxed{\bf a = \dfrac{9}{10}}[/tex]
[tex]\bf \boxed{\bf b = \dfrac{5}{3}}[/tex]
[tex]\bf \boxed{\bf c = 11}[/tex]
[tex]\bf d=\dfrac{5}{2}-\dfrac{5}{1}\implies d=\dfrac{5-5\cdot2}{2} \implies d=\dfrac{5-10}{2}\implies \boxed{\bf d=-\dfrac{5}{2}}[/tex]
Cel mai mic număr este [tex]\bf d= -\dfrac{5}{2}[/tex]
