A 6th-grade class did a weekend fitness challenge.
labwork [276]

Using percentages we can conclude that Amanda achieved 77.34% of her goal.

<h3>What is the percentage?</h3>

A percentage is a figure or ratio stated as a fraction of 100 in mathematics.

Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it.

A % is a number without dimensions and without a standard measurement.

For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

So, percent of goals Amanda achieved:

She exercised for 58 minutes.

Then,

58/75 * 100

77.34%

Therefore, using percentages we can conclude that Amanda achieved 77.34% of her goal.
