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 of girls to boys in this scenario is 5:1. This is determined by dividing the number of girls by the number of boys, which gives us 15 girls divided by 3 boys, resulting in a ratio of 5 girls to 1 boy.
5 girls to 1 boy
The ratio is: 3 to 4
8 to 7.
The ratio of 15 boys to 12 girls can be simplified by finding the greatest common divisor of 15 and 12, which is 3. Dividing both numbers by 3 gives us a ratio of 5 boys to 4 girls. This means for every 5 boys, there are 4 girls in the group.
3:4
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)
1 to 2 = 5 to 10 so 15 students in all.
