40% of the 25 students in the class are boys. Write 40% as a fraction? Then find the ratio of girls to boys in the class.
10 of the students are boys the ratio would be 10:15?
would 40% as a fraction be 4/10??
Those answers are correct.
Your teacher may want you to simplify them.
10:15 = 2:3
4/10 = 2/5
To write 40% as a fraction, you need to first understand that "percent" means "per hundred." So, 40% is equivalent to 40 per hundred, or 40/100. However, this fraction can be simplified. Both the numerator (40) and denominator (100) can be divided by 20, resulting in the simplified fraction of 2/5. Therefore, 40% can be written as the fraction 2/5.
Regarding the ratio of girls to boys in the class, you correctly mentioned that there are 25 students in total and 40% (10 students) are boys. Therefore, the number of girls can be found by subtracting the number of boys from the total number of students: 25 - 10 = 15. So, there are 15 girls in the class.
To find the ratio of girls to boys, you would write it as "girls:boys." In this case, there are 15 girls and 10 boys, so the ratio would be written as 15:10. However, this ratio can be simplified by dividing both sides by 5. The simplified ratio is 3:2.
To summarize:
- 40% as a fraction is 2/5.
- The ratio of girls to boys in the class is 3:2.
