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
