Question

Призерами городской олимпиады по математике стало 48 учеников, что составило 12% от числа участников. Сколько человек учавствовало в олимпиаде?

Answer 1

12%=0,12. Число по известной части находят делением 0,12/48=400

Answer 2

Calculation of the Total Number of Participants in the Math Olympiad

To find out how many people participated in the math Olympiad, we can use the information provided. It states that the number of students who became prize winners in the city math Olympiad was 48, which is 12% of the total number of participants.

Let's assume the total number of participants in the math Olympiad is represented by the variable "x". According to the given information, 12% of "x" is equal to 48.

To calculate the total number of participants, we can set up the following equation:

0.12x = 48

To solve for "x", we can divide both sides of the equation by 0.12:

x = 48 / 0.12

Now, let's calculate the value of "x":

x = 400

Therefore, there were 400 participants in the math Olympiad.
