Which of the following figures have least shaded part?

Options

A.
B.
C.
D.

Answer

To determine which figure has the least shaded part, we will analyze each option by calculating the fraction of shaded parts and converting them into decimals.

### Step-by-Step Solution:

1. **Option 1:**
- Count the shaded parts: 3 shaded parts.
- Count the total parts: 10 parts (3 shaded + 7 unshaded).
- Calculate the fraction of shaded parts:
\[ \text{Fraction} = \frac{3}{10} \]
- Convert the fraction to decimal:
\[ \frac{3}{10} = 0.3 \]

2. **Option 2:**
- Count the shaded parts: 6 shaded parts.
- Count the total parts: 12 parts (6 shaded + 6 unshaded).
- Calculate the fraction of shaded parts:
\[ \text{Fraction} = \frac{6}{12} \]
- Simplify the fraction:
\[ \frac{6}{12} = \frac{1}{2} \]
- Convert the fraction to decimal:
\[ \frac{1}{2} = 0.5 \]

3. **Option 3:**
- Count the shaded parts: 6 shaded parts.
- Count the total parts: 24 parts (6 shaded + 18 unshaded).
- Calculate the fraction of shaded parts:
\[ \text{Fraction} = \frac{6}{24} \]
- Simplify the fraction:
\[ \frac{6}{24} = \frac{1}{4} \]
- Convert the fraction to decimal:
\[ \frac{1}{4} = 0.25 \]

4. **Option 4:**
- Count the shaded parts: 8 shaded parts.
- Count the total parts: 24 parts (8 shaded + 16 unshaded).
- Calculate the fraction of shaded parts:
\[ \text{Fraction} = \frac{8}{24} \]
- Simplify the fraction:
\[ \frac{8}{24} = \frac{1}{3} \]
- Convert the fraction to decimal:
\[ \frac{1}{3} \approx 0.33 \]

5. **Compare the decimal values:**
- Option 1: 0.3
- Option 2: 0.5
- Option 3: 0.25
- Option 4: 0.33

The least value among these decimals is **0.25** from Option 3.

### Final Answer:
The figure with the least shaded part is **Option 3**.
