Final answer:
To model the decimal 0.53, you convert it to 53% for its percent equivalent and 53/100 for its fraction equivalent. The zeros before 53 are not significant, indicating two significant figures.
Step-by-step explanation:
Converting a Decimal to Percent and Fraction
To model the decimal 0.53, convert it to a percent and a fraction. To convert the decimal to a percent, simply move the decimal point two places to the right and add the percent symbol. Therefore, 0.53 becomes 53%.
To convert the decimal to a fraction, think of the decimal as being out of 1. Since there are two digits after the decimal, the denominator should be 100. Thus, 0.53 can be written as the fraction 53/100. This fraction is already in its simplest form and cannot be simplified further.
When dealing with significant figures, note that in the decimal 0.53, the zeros before the 53 are not significant. They are placeholders that locate the decimal point. There are two significant figures in 0.53.
