Percentage value can be found a way of multiplication of the first so in this example 20 to be increased on 100 to give 2000, and this result would be divided on 200 to give 10%.
To calculate percent from percent, to convert percent to shares 100, or decimal, and to increase them. For example, 500% from 400%:
(500/100) × (400/100) = 50 × 40 = 2000 = 2000/100 = 20%.
It isn’t correct to divide it on 100 and to use a Percent sign, at the same time. (For example, 15% = 15/100 = 0,15, instead of 15% / 100, which actually (15/100)/100 = 0,0015. The term such as (100/100) % also will be wrong, it can be read as (1) Percent even if the purpose consists to tell 100%. )
Every time when we speak about percent, it is important to specify that it is relative, i.e. that is the general that there correspond 100%. The following task illustrates this moment.
In this or that college of 50% of all students women, and 20% of all students of profession of the information scientist are. If 10% of female students for informatics of the majors, what percent of specialties to informatics make women?
We asked to calculate a ratio of women of specialties to informatics for all specialties to informatics. We know that 50% of all students make women, and among these 10% for specialties of informatics, thus, we conclude that (50/100) x (10/100) = 5/100 or 5% of all students are women, informatics majors.
At division of this size of 10% of all students who professions of the information scientist are, we come to the answer: 5% / = 50/100 or 50% from all specialties to informatics make of the woman.
