Which one of the following group is in descending order?

Options

A. `19/21 ,16/19, 11/14`
B. `11/14,19/21,16/19`
C. `19/21,11/14,16/19`
D. `11/14,16/19,19/21`

Answer

To determine which group of numbers is in descending order, we need to analyze the given options. Let's assume the options are as follows:

1. \( \frac{19}{21} \)
2. \( \frac{16}{19} \)
3. \( \frac{11}{19} \)
4. \( 14 \)

### Step 1: Convert the fractions to decimal form
To compare these numbers easily, we can convert the fractions into decimal form.

- For \( \frac{19}{21} \):
\[ \frac{19}{21} \approx 0.9048 \]

- For \( \frac{16}{19} \):
\[ \frac{16}{19} \approx 0.8421 \]

- For \( \frac{11}{19} \):
\[ \frac{11}{19} \approx 0.5789 \]

- For \( 14 \):
\[ 14 = 14.0 \]

### Step 2: List the values in decimal form
Now we have the following values:
1. \( \frac{19}{21} \approx 0.9048 \)
2. \( \frac{16}{19} \approx 0.8421 \)
3. \( \frac{11}{19} \approx 0.5789 \)
4. \( 14 = 14.0 \)

### Step 3: Compare the decimal values
Now we can compare these decimal values:
- \( 14.0 \) is the largest.
- Next is \( 0.9048 \) (which is \( \frac{19}{21} \)).
- Then \( 0.8421 \) (which is \( \frac{16}{19} \)).
- Finally, \( 0.5789 \) (which is \( \frac{11}{19} \)).

### Step 4: Arrange in descending order
Arranging these values in descending order gives us:
1. \( 14 \)
2. \( \frac{19}{21} \)
3. \( \frac{16}{19} \)
4. \( \frac{11}{19} \)

### Conclusion
The group in descending order is:
\[ 14, \frac{19}{21}, \frac{16}{19}, \frac{11}{19} \]
