To convert a decimal number to a percentage, you follow these steps:
1. Multiply the decimal number by 100. This moves the decimal point two places to the right, converting it into a whole number.
2. Append the percent sign (%) to the result, to indicate that the number is a percentage now.
For the decimal 2.47, we carry out the multiplication:
2.47 * 100 = 247
Once we have this result, we add the percent sign to get:
247%
Therefore, 2.47 as a percentage is 247%.
