number of boys = ratio of boys x total strength / total ratio = 5 x 27/9 = 5 x 3 = 15 number of girls = ratio of girls x total strength / total ratio = 4 x 27/9 = 4 x 3 = 12 verification: 15 + 12 = 27
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.
12
1 to 2 = 5 to 10 so 15 students in all.
45
18 boys and 12 girls
9 boys
It is 8 : 26.
6 = 2/12 = 1/6 so there are 36 in the class, 15 boys & 21 girls.
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
You add the two numbers together as the denominator and put one of the original numbers in the numerator. Example: The ratio of girls to boys in Class A is 2:3. Total number of children in the ratio: 2+3=5 You want to organize the information into: # of girls 2 ________________ = _____ Total # of children 5
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.
