In one class 46 percent of students are girls and 58 percent are boys how many girls and how many boys in the class?
It is not opssible to give a sensible answer to this question. 46+58 = 104. So if the class has 46% girls and 58% boys then the class has 4% who are simultaneously girls and boys.
How many girls are in the class room if 60 percent of 30 students in the class were girls?
17. There should be 18, but one has gone to the toilet.
There are twice as many girls as boys in a chemistry class If 50 percent of the girls and 80 percent of boys have finished the test what percent are still working on the test?
Still working on the test. At first glance you know that at least one third of the class is still working on it (half the girls are one third of the class). And since over half the boys have finished, you know the total remaining is less than half. You can figure it out using any numbers to set it up, but let's use 20 girls and 10 boys as the simplest. So 10 girls and 8 boys have finished for a total of 18, which leaves 12 still working on it. 12/30 is 6/15ths which is 2/5ths which is the same as 40%.
How many girls are in Feeling This Class if the ratio of boys to girls is 12 to 3 and there are 24 students in the class?
If the ratio of boys to girls is 12 to 3, then the total ratio is 12 + 3 = 15. To find how many girls are in the class, we divide the number of girls by the total ratio, 24 / 15 = 1.6. This means there are approximately 1.6 girls in the class. However, since we can't have a fraction of a girl, we can conclude that there are 2 girls in the class.
How do you convert percent to a ratio?
Ratios are good for comparing two quantities. Like in a classroom, the ratio of girls to boys, for example. Say the class has 40 students, and 22 of them are girls, so this is 22/40 = 55% of the class. But the ratio is comparing the girls to the boys, not the entire class. So if there are 55% girls, then 100% - 55% = 45% boys. Now the ratio can be made of 55 : 45 girl to boy ratio. This can be simplified to a 11:9 ratio.

What would be the ratio of boys to girls if there are 24 girls in a class of 65?
Two ways to look at it: 65 - 24 = 41, or 24 girls to 41 boys (ratio is 24:41). Or you could show the percentage of the girls in the class by using fraction and converting to decimal or percent: 24/65 of the class are girls. Divide 24 by 65 to set it up as a decimal and then as percent. 24/65 = 0.3692307 (round off to 0.37) which would be 37%.
If 30 percent of a class consists of boys and there are 49 girls how many boys are there?
