## Enter estimate statement:

Perform the following calculations on 3.31

Estimation, Accuracy, Precision, Percentage conversion, Truncate

##### Step 1: Look at the decider digit:

Decider Digit = 1st decimal place

The first decimal place in 3.31 is 3

##### Step 2: Evalute the decider digit (3):

Since 3 is < 5, we round down to 3

3.31 estimated is 3

##### Convert 3.31 to a percentage

Percentage = 100% * 3.31

Percentage = 331%

##### Convert 3.31 to a fraction

2 decimal places means we multiply by 102

 102 * 3.31 102

 100 * 3.31 100

Fraction = 331/100

##### Write 3.31 in word notation

3.31 = three point three one

##### Calculate the floor of 3.31

The floor is the greatest integer less than or equal to 3.31

##### Calculate the ceiling of 3.31

The ceiling is the least integer greater than or equal to 3.31

Determine the precision and accuracy (scale) of 3.31

Take precision first and then accuracy

##### Precision Definition:

The number of digits in the number

##### Precision Calculation for 3.31:

3.31 has 3 digits listed below

Digit 1 → 3

Digit 2 → 3

Digit 3 → 1

Precision = 3

##### Accuracy Definition:

The number of digits to the right of the decimal point

##### Accuracy Calculation for 3.31:

Digit to the right of the decimal place 1 → 3

Digit to the right of the decimal place 2 → 1

Accuracy = 2

Truncate 3.31

Do it to 1 decimal places

##### Truncate Definition:

Chop off decimal places

##### Evaluate decimal places:

Keep the 1 decimal in red

Drop the decimal places in black

3.31

3.31 truncated to 1 decimal place = 3.3

Truncate 3.31

Do it to 2 decimal places

##### Truncate Definition:

Chop off decimal places

##### Evaluate decimal places:

Keep the 2 decimals in red

Drop the decimal places in black

3.31

3.31 truncated to 2 decimal places = 3.31

3.31 estimated is 3
Percentage = 331%
Fraction = 331/100
3.31 = three point three one
Accuracy = 2
3.31 truncated to 1 decimal place = 3.3
3.31 truncated to 2 decimal places = 3.31

##### What is the Answer?
3.31 estimated is 3
Percentage = 331%
Fraction = 331/100
3.31 = three point three one
Accuracy = 2
3.31 truncated to 1 decimal place = 3.3
3.31 truncated to 2 decimal places = 3.31
