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.

Round the answer to the appropriate number of significant figures. The time to complete the process depends on the student's math skills and the use of a calculator.
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.
Full Answer >To write a decimal as a fraction, first write a fraction with the decimal as the numerator and the integer one as the denominator. Then perform a mathematical operation on the fraction to get rid of the decimal point and simplify the fraction.
