To calculate the percentage represented by a ratio, divide the numerator by the denominator, and multiply by 100. For example, given the ratio 14 out of 50, the corresponding percentage is found by dividing 14 by 50, which is 0.28, then multiplying 0.28 by 100 to get 28 percent.
Know MoreThe word percent means "for every hundred," so finding a percent is the same as restating a rational number so that its denominator is 100. The ratio 14/50 can be converted to a percent by multiplying the numerator and denominator by 2, yielding the ratio 28/100, or 28 percent. Decimal numbers are converted to percents by moving the decimal point two places to the left. For example, 0.73 equals 73 percent.

Full Answer >To turn a fraction into a mixed number, you must divide the fraction's numerator by its denominator. Use the number of times the denominator goes into the numerator to represent the whole number, and then use the remaining number to represent the new numerator.
Full Answer >A unit fraction is a fraction where the top number, known as the numerator, is one, and the bottom number, known as the denominator, is any positive number. Additionally, the denominator must be an integer, or round number.
Full Answer >To change an improper fraction into a mixed number, divide the numerator by the denominator and use the resulting quotient, remainder and divisor as the whole numeral, numerator and denominator, respectively. The mixed number makes clear how many complete wholes and fractional parts are present.
