Worksheet: Percentages to Decimals
In this worksheet, we will practice converting percents to decimals for a set of rational numbers.
Express as a decimal.
A percent is a fraction where the denominator (i.e., the whole) is 100. In the diagram, a 100-centimeter ruler has been used to represent the whole.
What is the length of the shaded part in centimeters? What percent of the ruler is it?
If now we use meter as a length unit and the ruler is one meter long, what is the length of the shaded part in meters?
- A0.4 m
- B0.3 m
- C0.25 m
- D0.75 m
- E0.7 m
The ratio of the length of the shaded part to that of the whole ruler can be expressed as a fraction, a percent (which is a fraction where the denominator is 100), or as a decimal. In the latter case, the decimal can be interpreted as the length of the shaded part when the whole is 1. Give this ratio as a decimal.
What fraction of a number is equivalent to ?
If of a certain number is added to it, and then of the total is subtracted from the result, would the result be greater than, less than, or equal to the original number?
- Agreater than the original number
- Bless than the original number
- Cequal to the original number
