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.

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.
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.
Number of primes = 4 Number of composites = 5 Ratio of primes to composites = 4 : 5
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.
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%
Multiply both number by any non-zero number and you will get an equivalent ratio.

Yes because 4/5 is a fraction and only rational numbers can be expressed as fractionsYes. It's the ratio of 4 to 5 .
