What is the boy-girl ratio in the class was 5 to 4 If there were 27 students how many boys were there?
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
What is the answer to this question The boy to girl ratio in the class was three to five . If there were twenty four students how many boys were there?
If the boy to girl ratio in the class is 3:5, this means that for every 3 boys, there are 5 girls. To find the number of boys in the class, you need to divide the total number of students by the total parts of the ratio (3+5=8) to get the value of each part. Then multiply this value by the number of parts representing boys (3) to find the number of boys. Therefore, in a class of 24 students, there would be 9 boys (24/8=3, 3x3=9).
What is the ratio of girls to boys if there is 5 girls to 9 boys?
5:9, dumb question!
What is the trick for working out ratios and proportion?
the trick for working ratio and proportions out is to,eg, say if there 5 girls in a class and the ratio of how many boys was 5:1 there will be 25 boys because you simply have to do 5x5=25 then simply times it by one .i think
How do you use the word ratio in a sentence?
