if there are 28 students in a class and there are 13 girls, what percentage of the class is girls?
( 13 / 28 ) * 100 % = 0.4643 * 100 % = 46.43 %
13/28 x 100%
=46.4%(corr. to 3 sig. fig.)
(we usually correct to 3 significant figure if we see long decimals)
To find the percentage of girls in the class, you can use the formula:
Percentage = (Number of girls / Total number of students) * 100
In this case, the number of girls is 13 and the total number of students is 28.
Let's plug those values into the formula:
Percentage = (13 / 28) * 100
Calculating, we get:
Percentage = 0.4642857142857143 * 100
Therefore, the percentage of girls in the class is approximately 46.43%.
To find the percentage of girls in the class, you need to divide the number of girls by the total number of students in the class, and then multiply by 100 to convert it to a percentage.
In this case, there are 13 girls and a total of 28 students.
Step 1: Divide the number of girls by the total number of students: 13 / 28 = 0.4643 (rounded to four decimal places).
Step 2: Multiply the result by 100 to convert it to a percentage: 0.4643 * 100 = 46.43%.
So, 46.43% of the class is girls.
