146 students.... 84 boys. Meaning there are 84 boys and 62 girls.
(146-84=62)
84 divided by 62 is 1.355.
Meaning 1.355 boys to every 1 girl.
If you mean ratio then I don't quite understand the question.. but if you mean RADIUS Then you take the diameter and divide it by two. ============================================== There's no such thing as the ratio of circles. You can find the ratio of their diameters, the ratio of their radiussesses, and the ratio of their areas. -- The ratio of their diameters is: One diameter divided by the other one. -- The ratio of their radiusses is the same number as the ratio of their diameters. -- The ratio of their areas is the square of that same number.
The answer depends on whether or not the shapes are similar. If they are, then the ratio of volumes is the cube of the ratio of the linear dimensions.
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
Their perimeters are in the same ratio.
There would be 6 boy students and 18 girl students in the class.
42:31

If there are 24 girls in a class of 50 and we assume the remaining students are boys, then there are 26 boys and the ratio of boys to girls is 26boys/24girls = 13/12=1.08333 boys for each girl.
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
62.5
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.
9 boys
If the ratio of girls to boys is 5:4, then out of the total of 108 students, 5/9 are girls and 4/9 are boys. Therefore, the number of girls is 108 x (5/9) = 60.

18 boys and 12 girls
