Round off to the second digit after the decimal point

e.g 23.77

the percentages to the first digit before the decimal point.
e.g 19.8%

are those correct?

23.77 looks good

19.8 is rounded to the 1st digit after the decimal point ...

@oobleck, it says first digit before the decimal point so it would be 19.8? seems correct no?

To round off a number to the second digit after the decimal point, you can follow these steps:

1. Identify the digit in the third place after the decimal point.
2. If this digit is 5 or greater, increase the digit in the second place by 1. If it is less than 5, leave the digit in the second place as it is.
3. Remove all digits after the second decimal place.

Using the example number 23.77:

1. The digit in the third place after the decimal point is 7.
2. Since 7 is greater than 5, we increase the digit in the second place (7) by 1, resulting in 8.
3. Removing all digits after the second decimal place gives us the rounded-off number 23.78.

Regarding percentages, to round them off to the first digit before the decimal point, follow these steps:

1. Identify the digit in the second place after the decimal point.
2. If this digit is 5 or greater, increase the digit in the first place by 1. If it is less than 5, leave the digit in the first place as it is.
3. Remove all digits after the decimal point.

Using the example percentage 19.8%:

1. The digit in the second place after the decimal point is 8.
2. Since 8 is greater than 5, we increase the digit in the first place (1) by 1, resulting in 2.
3. Removing all digits after the decimal point gives us the rounded-off percentage 20%.

Therefore, the rounded-off values you provided are correct: 23.77 rounded off to the second digit after the decimal point is 23.78, and 19.8% rounded off to the first digit before the decimal point is 20%.
