1) $\mathbf{\dfrac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{2}}}$ = $\mathbf{0{,}\textcolor{#ef4444}{5}}$

1 ÷ 2 = $\mathbf{0{,}\textcolor{#ef4444}{5}}$ , ou ainda $\mathbf{\dfrac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{2}}}$ = $\mathbf{\dfrac{\textcolor{#ef4444}{5}}{\textcolor{#3b82f6}{10}}}$ = $\mathbf{0{,}\textcolor{#ef4444}{5}}$ .

2) $\mathbf{\dfrac{\textcolor{#ef4444}{3}}{\textcolor{#3b82f6}{4}}}$ = $\mathbf{0{,}\textcolor{#ef4444}{75}}$

3 ÷ 4 = $\mathbf{0{,}\textcolor{#ef4444}{75}}$ , ou ainda $\mathbf{\dfrac{\textcolor{#ef4444}{3}}{\textcolor{#3b82f6}{4}}}$ = $\mathbf{\dfrac{\textcolor{#ef4444}{75}}{\textcolor{#3b82f6}{100}}}$ = $\mathbf{0{,}\textcolor{#ef4444}{75}}$ .

3) $\mathbf{\dfrac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{5}}}$ = $\mathbf{0{,}\textcolor{#ef4444}{2}}$

1 ÷ 5 = $\mathbf{0{,}\textcolor{#ef4444}{2}}$ , ou ainda $\mathbf{\dfrac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{5}}}$ = $\mathbf{\dfrac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{10}}}$ = $\mathbf{0{,}\textcolor{#ef4444}{2}}$ .

4) $\mathbf{0{,}\textcolor{#ef4444}{2}}$ = $\mathbf{\dfrac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{10}}}$

O algarismo 2 está na ordem dos décimos, então corresponde à fração $\mathbf{\dfrac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{10}}}$ .

5) $\mathbf{0{,}\textcolor{#ef4444}{25}}$ = $\mathbf{\dfrac{\textcolor{#ef4444}{25}}{\textcolor{#3b82f6}{100}}}$

Os algarismos 2 e 5 estão respectivamente nas ordens dos décimos e centésimos. Lendo as 2 casas juntas: 25 centésimos = $\mathbf{\dfrac{\textcolor{#ef4444}{25}}{\textcolor{#3b82f6}{100}}}$ .

6) $\mathbf{0{,}0\textcolor{#ef4444}{1}}$ = $\mathbf{\dfrac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{100}}}$

O 0 ocupa a ordem dos décimos, e o 1 ocupa a ordem dos centésimos. Logo, $\mathbf{0{,}0\textcolor{#ef4444}{1}}$ = $\mathbf{\dfrac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{100}}}$ .
