Final answer:
The word percent does mean 'per 100', which is true. It originates from Latin and denotes a fractional number with a denominator of 100. Percent calculations are widely used in various real-life scenarios and mathematical problems.
Step-by-step explanation:
The statement 'The word percent means per 100' is true. The term percent derives from the Latin phrase 'per centum', which means 'per hundred'. A percent is a way of expressing a number as a fraction of 100. The percent symbol (%) denotes this fractional number. For instance, 25% represents the fraction 25/100, and 100% represents a whole, or 1, since it is the equivalent of 100/100. Calculating a percent involves dividing the part by the whole and then multiplying by 100. This forms the basis for many calculations in mathematics and real life, such as determining sale discounts, calculating the concentration in percent, and assessing test scores, like if you score 96 out of 100 on a test, you have 96% correct.
