"70%" refers to a fraction that represents 70 out of 100 parts. It is commonly used to express a percentage, indicating a portion of a whole. For example, if a class of 100 students scored 70% on a test, it means that 70 students achieved a score that met or exceeded the passing criteria. In various contexts, such as statistics or surveys, 70% can indicate a significant majority. For instance, if 70% of respondents in a survey support a particular policy, it suggests that a large portion of the population favors that policy, reflecting a strong consensus.
