Question

Quizplus · Accepted Answer

Percent means "parts per hundred." Percent is a fraction, containing a variable numerator and a denominator that always equals 100. Therefore, 45% = 45/100 (fraction), 45:100 (ratio), and 0.45 (decimal). To determine the percent of the soda that the client drank, multiply 45%×
12 oz. Using the decimal format (0.45×
12), line up the numbers on the right. Do not align the decimal points. Starting at the right, multiply each digit in the top number by each digit in the bottom number, just as is done with whole numbers. Add the products. Place the decimal point in the answer by starting at the right and moving the point the same number of places that you totaled earlier. When blank spaces are present, fill each one with a zero. The answer is 5.4 oz (0.45×
12).
