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
The ratio of 15 over 12 is 5:4.
Well, isn't that a happy little math problem! If the ratio of girls to boys is 5 to 4, that means for every 5 girls, there are 4 boys. To find out how many girls in a class of 108 students, we first need to divide 108 by the total parts in the ratio (5+4=9), which is 12. Then, we multiply 108 by the girls' share (5/9) to find there are 60 girls in the class.

The ratio of 15 over 12 is 5:4.
It is: 20 to 25
Number of primes = 4 Number of composites = 5 Ratio of primes to composites = 4 : 5

Divide by 9 (4 + 5), then multiply by either 4 or 5 to get the first number. Subtract that number from the total to get the second number. Multiply the quotient from the first step by the other number (4 or 5) to check the second answer.
To find the number of boys in the class, we first need to determine the total number of students. Since the ratio of boys to girls is 5 to 8, the total parts of the ratio is 5 + 8 = 13. If there are 40 girls in the class, we can calculate the total number of students as 40 girls / 8 girls per part = 5 parts. So, the total number of students is 5 parts * 13 total parts = 65 students. To find the number of boys, we can calculate 65 total students - 40 girls = 25 boys in the class.
Multiply both number by any non-zero number and you will get an equivalent ratio.
A percent is a number relative to 100. Therefore, we want the number 100 in the ratio. In order to do that, we need to multiply BOTH numbers in the ratio by a number so that the second number of the new ratio is equal to 100. The first number of the new ratio is the percent. For example: 4:5 = [4*20]:[5*20] = 80:100 = 80%

If the ratio is 5:4, and the number of pupils is 27, this means that there are 5 + 4 = 9 ninths to the whole. Therefore, 5/9 x 27 is equal to 15 and 4/9 x 27 is equal to 12. There are therefore 15 girls and 12 boys.
Yes because 4/5 is a fraction and only rational numbers can be expressed as fractionsYes. It's the ratio of 4 to 5 .
