A palavra "de" entre as duas frações é sinal de multiplicação, então $\mathbf{\frac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{2}}}$ de $\mathbf{\frac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{3}}}$ é $\mathbf{\frac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{2}} \times \frac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{3}}}$ .

$\mathbf{\dfrac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{2}} \times \dfrac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{3}}}$

= $\mathbf{\dfrac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{6}}}$

= $\mathbf{\dfrac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{3}}}$

O resultado é $\mathbf{\frac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{6}}}$ da fita, que é o mesmo que $\mathbf{\frac{\textcolor{#ef4444}{1}}{\textcolor{#3b82f6}{3}}}$ . Como a barra tem 6 partes iguais, $\mathbf{\frac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{6}}}$ são 2 partes. Todas as partes são iguais, então qualquer combinação de 2 delas serve.

Resposta: pintar quaisquer 2 das 6 partes.
