Question

which model shows the fraction 3/4?

Explanation:

Step1: Recall fraction model

A fraction $\frac{a}{b}$ means a whole divided into $b$ equal parts, with $a$ parts shaded. For $\frac{3}{4}$, the whole should be divided into 4 equal parts, and 3 parts shaded.

Step2: Analyze each model

• First model: Divided into 4 parts, 2 shaded ( $\frac{2}{4}$ ), not $\frac{3}{4}$.
• Second model: Divided into 6 parts, 3 shaded ( $\frac{3}{6}$ ), not $\frac{3}{4}$.
• Third model: Divided into 4 parts, 3 shaded ( $\frac{3}{4}$ ), matches.

Answer:

The third circular model (with 4 equal parts, 3 shaded)
