At a school on Friday, 3 out of every 4 students were wearing jeans. There were 600 students at school on Friday. How
many of the students were wearing jeans?
A 599, because 600 – (4-3) = 599
B 450, because 3/4 = 450/600
C 50, because 600 ÷ (4 x 3) = 50
D 800, because 3/4 = 600/800
B 450,because 3/4=450/600
Gtb
B 45, because 3/4 =450/600
To find the number of students wearing jeans, we can use the fact that 3 out of every 4 students were wearing jeans.
Option A suggests subtracting 4-3 from the total number of students, which is incorrect because 4-3 does not give us the proportion of students wearing jeans.
Option B correctly states that 3/4 of the students were wearing jeans. To find the number of students wearing jeans, we can calculate (3/4) * 600 = 450. Therefore, Option B is the correct answer.
Option C suggests dividing the total number of students by (4 x 3). However, this calculation does not involve the given information about the proportion of students wearing jeans.
Option D equates the 3/4 ratio to 600/800, which is incorrect because the total number of students is given as 600, not 800.
Therefore, the correct answer is B: 450 students were wearing jeans.
