Sure! Let's go through each number step-by-step and round them to one decimal place.
### Step-by-Step Solution:
#### A) 2.888
1. Look at the first decimal place: 8.
2. Look at the second decimal place: 8.
3. Since 8 is greater than or equal to 5, we round the first decimal place up.
Therefore, 2.888 rounded to one decimal place is 2.9.
#### B) 1.438
1. Look at the first decimal place: 4.
2. Look at the second decimal place: 3.
3. Since 3 is less than 5, we keep the first decimal place as it is.
Therefore, 1.438 rounded to one decimal place is 1.4.
#### C) 8.358
1. Look at the first decimal place: 3.
2. Look at the second decimal place: 5.
3. Since 5 is greater than or equal to 5, we round the first decimal place up.
Therefore, 8.358 rounded to one decimal place is 8.4.
#### D) 52.39
1. Look at the first decimal place: 3.
2. Look at the second decimal place: 9.
3. Since 9 is greater than or equal to 5, we round the first decimal place up.
Therefore, 52.39 rounded to one decimal place is 52.4.
### Summary of Rounded Numbers:
- A = 2.9
- B = 1.4
- C = 8.4
- D = 52.4
