10 to 15 or 2 to 3 even
1 to 2 = 5 to 10 so 15 students in all.
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.
15:18 It can also be written as a fraction 15/18 Because there are 15 girls and 18 boys
The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%
Of the total 15 people 5 are boys and 10 are girls Boys are 5/15 = 1/3 Girls are 10/15 = 2/3 Ratio of boys to girls is 1 to 2
10 to 15 or 2 to 3 even
It is: 2 to 3
girls = 15 boys = 42 - 15 = 27 ratio of girls to boys = 15/27
The ratio is: 3 to 4
5 girls to 1 boy
for every one boy there are five girls
8 to 7.
3:4
5:4
Since the ratio of boys to girls is 5 to 8, the total ratio parts is 5 + 8 = 13. To find how many boys are in the class, divide the total number of girls (40) by the total parts of the ratio (13), then multiply by the number of boys parts (5). Thus, there are 15 boys in the class.
There is approximately 3 ways to write this ratio out. Those ways are of the following: 1. 15:9 2. 15 to 9 3. 15 over 9 (as if it is in a fraction)
