In a math class of 40 students, there are 21 female students. Which of the following does NOT represent a ratio of the number of girls in the classroom to the total number of students?
19/40
0.53
53%
21/40
19/40 because there is no number 19, and there is no math required to get another answer.
It asks for girls. 19 is boys I suspect.
21/40 = 0.525 which is 0.53 rounded to 2 figures
0.53 * 100 = 53 %
Thanks Again so much!
To determine which of the options does NOT represent a ratio of the number of girls in the classroom to the total number of students, we need to identify the correct ratio and then compare it to the given options.
The ratio of the number of girls to the total number of students is 21/40, as there are 21 girls out of 40 students.
Now let's analyze the options:
1. 19/40: This represents the ratio of 19 girls out of 40 students. This is a valid representation of the ratio of girls to the total number of students.
2. 0.53: This decimal value is equivalent to 53/100, which represents the ratio of 53 girls out of 100 students. This is another valid representation of the ratio of girls to the total number of students.
3. 53%: This percentage is also equivalent to 53/100, which represents the ratio of 53 girls out of 100 students, just like the previous option. Therefore, this is a valid representation of the ratio of girls to the total number of students.
4. 21/40: This is the same ratio that we initially identified as the correct one. This option represents the correct ratio of girls to the total number of students.
Therefore, none of the options (19/40, 0.53, 53%, and 21/40) do NOT represent the ratio of the number of girls in the classroom to the total number of students.
