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

Draw 3.31 on a number line:

Calculate the floor of 3.31

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

Calculate the Floor for 3.31 = 3

Calculate the ceiling of 3.31

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