Explain the term percentage of the number?
- A value or ratio that may be stated as a portion of 100 is referred to as a percentage in mathematics.
- If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
- The proportion ultimately refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
As the stated question-
Average number of waking hour per day = 16.
Communicating hours = 70% of total hours.
Thus,
Communicating hours = 70 x 16 / 100
Communicating hours = 11.2 hours
Thus, the total number of hours spend on the communicating is 11.2 hours.
