Para comparar $\mathbf{\dfrac{2}{3}}$ e $\mathbf{\dfrac{3}{4}}$ , convertemos ambas em frações equivalentes com denominador 12 (múltiplo comum de 3 e 4).

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

= $\mathbf{\dfrac{\textcolor{#ef4444}{2} \times 4}{\textcolor{#3b82f6}{3} \times 4}}$

= $\mathbf{\dfrac{\textcolor{#ef4444}{8}}{\textcolor{#3b82f6}{12}}}$

ᅠ

$\mathbf{\dfrac{\textcolor{#ef4444}{3}}{\textcolor{#3b82f6}{4}}}$

= $\mathbf{\dfrac{\textcolor{#ef4444}{3} \times 3}{\textcolor{#3b82f6}{4} \times 3}}$

= $\mathbf{\dfrac{\textcolor{#ef4444}{9}}{\textcolor{#3b82f6}{12}}}$

Comparando: $\mathbf{\dfrac{\textcolor{#ef4444}{8}}{\textcolor{#3b82f6}{12}}}$ < $\mathbf{\dfrac{\textcolor{#ef4444}{9}}{\textcolor{#3b82f6}{12}}}$ , então $\mathbf{\dfrac{\textcolor{#ef4444}{2}}{\textcolor{#3b82f6}{3}}}$ < $\mathbf{\dfrac{\textcolor{#ef4444}{3}}{\textcolor{#3b82f6}{4}}}$ . A maior das duas frações é $\mathbf{\dfrac{3}{4}}$ , equivalente a $\mathbf{\dfrac{\textcolor{#ef4444}{9}}{\textcolor{#3b82f6}{12}}}$ .

Logo, basta pintar 9 das 12 partes do painel para representar a fração maior.

Resposta: selecionar quaisquer 9 das 12 partes da figura.
