If there are 4 girls the ratio would be 7:1. I don't see how you could have 4.7 of somebody, but if it were possible the ratio would be 5.9:1
The ratio of girls to total students is 15:25, or 3:5. Three out of five students are girls so there would be a 60% probability that a girl would be chosen; a 2 out of 5 chance, or 40% probability that a boy would be chosen.
Examples are:a ratio can also show a part compared to the whole lot. For example there are 5 pups, 2 are boys and 3 are girls, then the ratio of boys to girls 2/3, the ratio of boys to total is 2/5, the ratio of girls to total is 3/5.a ratio can also be used in drawings. For example to draw a horse with a scale 1/10 from its normal size. Another example is that the height to width ratio of the Indian Flag is 2:3 or 2/3Another examples are:1/2, 3/4, 78/89, ... etcx/(x+1), y/(y-2), ... etc.
Assuming boys are equally as likely as girls, 125 boys would be expected. The probability of getting 140 or fewer boys is approximately 97.51%
The male to female human sex ratio varies, due to demographics, environment, sex deterministic abortion, and imbalance in the male/female sperm viability ratio. The secondary ratio of boys to girls is about 105 to 100, or about 0.525 male. Estimates of the current birth sex ratio is about 0.535 male. The current global sex ratio (population) is about 0.507 male (2010) to 0.508 male (projected 2011).
Driver insurance rates are higher for boys than for girls because it has been proven statistically that boys are more likely to get into car accidents than girls.
2 to 3
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.
If there are 125 boys and 25 girls, then the ratio of boys to girls would be 5:1.
The ratio of girls to boys in this case would be 10:1
It is already in its simplest ratio because 17 is a prime number but if it were 7 boys to 21 girls then the ratio would be 1 to 3
A ratio of boys to girls was 3 to 7 and there were 200 more girls than boys there would of been 150 boys that enrolled in school this year. This is a math problem.
The ratio of girls to boys is 21/14 = 3/2 = 1.5 . The ratio of boys to girls is 14/21 = 2/3 = 0.66 .
2 boys for every 3 girls 8 boys / 2 boys = 4 times the original ratio 4 times original ratio x 3 girls = 12 girls
The ratio is 9:12 (girls:boys)Simplified the ratio is 3:4 When there are 24 girls, there will be 32 boys. (3:4 = 24:32)
There is 48 Girls and 51 boys
In a class of 30, if there are 12 boys then there must be 18 girls. This would make the ratio: 18:12 or 3:2 (girls:boys)
Expressed as a ratio in its simplest form, 10 boys to 25 girls are in the ratio 2:5.
