To convert a decimal to a percentage, you multiply the decimal by 100. This is because "percent" means "per hundred", so you are essentially expressing the decimal as parts per hundred.
Given the decimal 0.75, let’s follow the steps to convert it to a percentage:
1. Start with the decimal 0.75.
2. Multiply the decimal by 100:
[tex]\[ 0.75 \times 100 = 75 \][/tex]
Therefore, the decimal 0.75 is represented as 75%.
Thus, from the given choices, the correct answer is:
O 75%
