d) 48%

Answer 1

c.52% 'cause,
no. of total students =25
no. of girls= 13
13/25×100=52%

Answer 2

The correct answer is c) 52%

Step-by-step explanation:

Percentages represent fractions or proportions in a population by using a ratio from 0 to 100. In this type of mathematical expression, the total population represents 100%; this means the 100% in the case presented is 25 considering there are 25 students in total (12 boys + 13 girls = 25 students). Due to this, if you want to know what percent of the students are girls, you should multiply 100 by 13 (number of girls) and then divide the result into 25 (total of students) which is equivalent to 52%. This can be expressed through the rule of three as

100% = 25 students

? = 13 students (girls)

100 x 13 / 25 = 52%
