Final answer:
To change the decimal 0.98 to a percent, multiply it by 100 to get 98, then add the percent symbol to express it as 98%.
Step-by-step explanation:
To convert the decimal 0.98 to a percent, we multiply it by 100. This is because percent means per hundred, and multiplying by 100 effectively shifts the decimal point two places to the right. Therefore, 0.98 multiplied by 100 gives us 98.
Just as the example given where 45.86 is multiplied by 100 to get 4586, converting a decimal to a percent follows the same principle. The conversion from decimals to percents is a straightforward process:
- Start with the decimal number, in this case, 0.98.
- Multiply the decimal by 100 to shift the decimal point two places to the right: 0.98 x 100 = 98.
- Attach the percent sign (%) to denote the percentage: 98%.
Thus, the decimal 0.98 is equivalent to 98%.
