Understanding Decimal Places
A number can be approximated to a certain number of decimal places as well (d.p.). The number of digits printed following a decimal point is referred to as decimal places.
Examples:
1. Give 7.763 to 1 decimal place
After the decimal point, the answer must be written with one digit. However, the second digit after the decimal point must be regarded as well. If the number is five or more, the first digit is rounded up.
7.763 is expressed as 7.8 to 1 d.p., for example.
2. Give 5.574 to 2 d.p.
After the decimal point, the answer should be presented with two digits. The third digit following the decimal point must be considered in this scenario. The second digit is not rounded up since the third digit after the decimal point is less than 5.
5.574, for example, is expressed as 5.57 to 2 d.p.
