Fraction to Decimal Conversion

Converting a fraction to a decimal involves dividing the numerator by the denominator. For example, dividing 8 by 5 gives 1.6. This step is essential because percentages are based on decimal values.

Understanding Percentages

A percentage represents a number out of 100. To express a decimal as a percent, multiply it by 100. For instance, 1.6 multiplied by 100 equals 160%, which means 8/5 is 160%.

Interpreting Improper Fractions

An improper fraction has a numerator larger than the denominator, indicating a value greater than one. Recognizing this helps anticipate that the percentage will be over 100%, as in the case of 8/5.
