n Ursula’s class 5/12 of the students are boys. If there are 36 students in her class, how many of them are girls?
anonymous 900 is right
if 5/12 of the class is boys, then
7/12 of the class are girls.
(7/12)(36) = 21
5:7 is the ratio of boys to girls
5/12 x 36
= 15 boys
so if 5/12 = 15
then 7/12 x 36
= 21 girls
To find out how many of the students in Ursula's class are girls, we first need to determine how many students are boys since we already know the total number of students.
Given that 5/12 of the students are boys, we can calculate the number of boys by multiplying the fraction (5/12) by the total number of students (36):
Boys = (5/12) * 36
To simplify the calculation, we can simplify the fraction (5/12):
Boys = (5/12) * 36 = 15
So, there are 15 boys in Ursula's class.
To find the number of girls, we subtract the number of boys from the total number of students:
Girls = Total students - Boys
Girls = 36 - 15 = 21
Therefore, there are 21 girls in Ursula's class.
Hope this helps!
