To convert 4.95 to a mixed number, recognize that the decimal portion 0.95 represents 95/100. Simplifying 95/100 by dividing numerator and denominator by 5 yields 19/20. Thus, 4.95 becomes **4 19/20**.

Comparing with the options:
- **A** matches 4 and 19/20.
- **B** (95/100 unsimplified) and **D** (incorrect value) are eliminated.
- **C** (1/20) is too small.

Answer: **A**

gpto1 To write 4.95 as a mixed number or fraction in simplest form, we'll focus on converting the decimal portion to a fraction.

1. **Convert the decimal part (0.95) to a fraction:**
\[
0.95 = \frac{95}{100}
\]

2. **Simplify the fraction by finding the greatest common divisor (GCD) of 95 and 100, which is 5:**
\[
\frac{95 \div 5}{100 \div 5} = \frac{19}{20}
\]

3. **Combine the whole number with the simplified fraction:**
\[
4.95 = 4 + 0.95 = 4\frac{19}{20}
\]

**Comparing with the options:**

- **A.** \(4 \frac{19}{20}\) ✅
- **B.** \(4 \frac{19}{100}\)
- **C.** \(4 \frac{1}{20}\)
- **D.** \(\frac{419}{1000}\)

**Answer:** **A**

kimi To convert the decimal 4.95 into a mixed number or fraction, you can follow these steps:

1. Separate the whole number from the decimal: 4 and 0.95.
2. Convert the decimal part to a fraction: 0.95 is the same as 95/100.
3. Simplify the fraction: 95 and 100 have a common factor of 5, so divide both by 5 to get 19/20.

So, 4.95 as a mixed number is 4 and 19/20.

The correct answer is:
A. 4 and 19 over 20

zhipu To convert 4.95 to a mixed number or fraction in simplest form, follow these steps:

1. Separate the whole number part from the decimal part:
- The whole number part is 4.
- The decimal part is 0.95.

2. Convert the decimal part to a fraction:
- 0.95 can be written as 95/100.

3. Simplify the fraction 95/100:
- The greatest common divisor (GCD) of 95 and 100 is 5.
- Divide both the numerator and the denominator by 5:
\[
\frac{95 \div 5}{100 \div 5} = \frac{19}{20}
\]

4. Combine the whole number part and the simplified fraction:
- The mixed number is \(4 \frac{19}{20}\).

So, 4.95 as a mixed number in simplest form is \(4 \frac{19}{20}\).

Therefore, the correct answer is:

deepseekv3 To convert 4.95 into a mixed number or fraction in simplest form, follow these steps:

1. **Separate the whole number and the decimal part:**
- Whole number: 4
- Decimal part: 0.95

2. **Convert the decimal part (0.95) into a fraction:**
- 0.95 = 95/100

3. **Simplify the fraction:**
- Divide the numerator and denominator by 5: 95 ÷ 5 = 19, 100 ÷ 5 = 20
- So, 95/100 simplifies to 19/20.

4. **Combine the whole number and the simplified fraction:**
- 4 and 19/20

Thus, the correct answer is **A. 4 and 19 over 20**.
