100 boys.
Ratio boys to girls is 2:3 ⇒ 2 parts are boys, 3 parts are girls. So there are 2 + 3 = 5 parts in all.
250 people ÷ 5 parts = 50 people per part
Boys: 2 parts x 50 people per part = 100 boys
Girls: 3 parts x 50 people per part = 150 girls
Ratio = 250/300 or 5/6
The ratio would be 6/5 in simplest form
To find 650 in the ratio of 5:8, you first need to add the parts of the ratio (5+8=13). Then, you divide 650 by the total parts of the ratio (650/13=50). Finally, you multiply this result by the individual parts of the ratio to find the corresponding values: 550=250 and 850=400. Therefore, 650 in the ratio of 5:8 is 250:400.
It is 21/250.
250 : 450 = 5 : 9
Ratio = 250/300 or 5/6
The ratio would be 6/5 in simplest form
Roughly 1 in every 250 people suffer from anorexia. Of those people, 90% are girls and 10% are boys.
total of pupils 45+36+64+105= 250 36 out of 250 are German boys the percentage of German boys is: (36X100) : 250 = 14.4 You can use the same method to calculate the percentage of French girls, which is approximately 25%.
1 out of every 250 people has anorexia. (girls to boys is 9 : 1) In the US, that is about 8 million people.
Anorexia usually affects 1 in every 250 people. (Girls : Boys, 9 : 1)
The actual statistic is 1 out of every 250 people are anorexic (90% are girls, 10% are boys). So, that is the equivalent to 0.4 out of every 100.
two hundred and fifteen 250 - 35 = 215
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%
24. 150:250 = 174 : 290
