Question

21 students in michael's classroom are wearing jeans. there are 25 students in his class.michael says that 80% of his class is wearing jeans.is michael correct ? explain your reasoning.

Answer 1

No, Michael would not be correct. 84% of his class would be wearing jeans. I divided 21 by 25, which came out to be .84.

Answer 2

There are a total of 25 students in Michael's classroom. Given 21 students are wearing jeans.

Michael said that 80% of his class is wearing jeans.

So we can get the number of students wearing jeans by finding 80% of 25 students.

80% of 25 = 25 × 80/100 = 2000/100 = 20

So 80% of 25 students is 20 students.

But given 21 students are wearing jeans.

So, Michael is not correct as 21 students are not 80% of his classroom.
