A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the decimal representation of 1556 is 1556, exactly as in the question.
It is already a decimal in the form of 78.5
21 in decimal form can be 21.0 or 21.00 or 21.000, or however many zeros you'd like to write after the decimal point.
% rate can be changed to decimal form. To convert % rate to decimal form: 1. Remove the % sign 2. Divide the given % by 100. Example: 25% = 0.25 in decimal
3.1415926 . . .
0.01
It is 0.06
0.02
1.5
0.13
.150
0.105/50:= 5 ÷ 50= 0.10 in decimal
Five thousands in decimal form would be 5000.00 (to two decimal places) If you meant Five Thousandths, then it would look like 0.0005.
