Answer 1

Boa noite!

Solução!

Fração impropria é quando o numerador é maior que 1.

Modelo!

$\boxed{a ~~ \dfrac{b}{c} = \dfrac{c.a+b}{c}}\\\\\\\\ A)~~1\dfrac{1}{2}= \frac{2.1+1}{2}= \dfrac{3}{2} \\\\\\\\\ B)~~2 \dfrac{1}{3}= \frac{3.2+1}{3} = \dfrac{7}{3}\\\\\\\\ C)~~ 3 \dfrac{2}{3}= \frac{3.3+2}{3} = \dfrac{11}{3}\\\\\\\\ D)~~ 5 \dfrac{3}{4}= \frac{5.4+3}{4} = \dfrac{23}{4}\\\\\\\\ E)~~ 2 \dfrac{2}{5}= \frac{5.2+2}{5} = \dfrac{12}{5}\\\\\\\\ F)~~ 4 \dfrac{1}{2}= \frac{2.4+1}{2} = \dfrac{9}{2}\\\\\\\\ G)~~ 5 \dfrac{4}{5}= \frac{5.5+4}{5} = \dfrac{29}{5}$


$H)~~ 2 \dfrac{5}{6}= \dfrac{6.2+5}{6} = \dfrac{17}{6}\\\\\\\\ I)~~ 1 \dfrac{2}{4}= \dfrac{4.1+2}{4} = \dfrac{6}{4}= \dfrac{3}{2} \\\\\\\\ J)~~ 3 \dfrac{4}{5}= \dfrac{5.3+4}{5} = \dfrac{19}{5}$

Boa noite!
Bons estudos!
