There are 900 students in a school. 540 of them are boys. what percent of the students in the school are boys?

There are 900 students in a school and 540 of the students are boys. What percent of the students are boys.

The fraction represents the 540 students that are boys out of all the students in the school. To find what percent of students are boys, we can turn into a percent.

To turn into a percent, we can divide both the numerator and denominator by the Greatest Common Factor of 540 and 900 using 180.

Now, we have our reduced fraction which is .

3 ÷ 5 = 0.6

0.6 × 100 = 60%

Therefore, 60% of the students in the school are boys.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
