Proportionately, Maris has used <u>630 minutes</u>, which represents 45 percent of the total minutes on her cell phone.
<h3>What is a percentage?</h3>
A percentage refers to the proportion or ratio of a value when compared with another value.
Like proportions, ratios, and other fractional value representations, percentages show the relative value or quantity contained in the whole.
Percentages are computed by dividing the numerator (the proportional value) by the denominator (the whole absolute value) and multiplying the product by 100.
The total minutes on Maris' cell phone = 1,400
The percentage of the minutes used = 45%
The absolute value of the percentage in minutes = 630 (1,400 x 45%)
Thus, we can show Maris that she has used <u>630 minutes</u> or, proportionately, 45 percent of the 1,400 minutes.
