12 boys, 15 girls The composite numbers bit is irrelevant. b+g=27 g-b=3 add the equations b+g+g-b=27+3 2g=30 g=15

How do you find the percentage?

This depends on what two numbers you have. For example, a question might ask in this form "If a classroom has 18 boys and 12 girls, what is the percentage of boys?" To work this out you need to add the boys and girls together so that you know the total number of children in the class... in this case 30. Next you multiply 18 by 100 and divide the result by 30 18 x 100 = 1800 - 1800 / 30 = 60% In other cases the question might ask for a percentage of a number you are given "If there are 350 cars in a carpark, and 40% of them are red, how many cars of other colours are there in the carpark. To work this out we need to either find out what 40% of 350 is and subtract it from 350, or we need to find out what 100% - 40% is and multiply that by 350. 350 x 40% = 350 x 0.4 = 140 - 350 - 140 = 190. 190 cars are not red. or 100% - 40% = 60% - 350 x 60% = 350 x 0.6 = 190.

What is the definition of ratio?

Let me use money as an example. You are familiar with US dollars and quarters? I hope so. There are 4 quarters in a dollar. The ratio of quarters to dollars is 4 to 1, written as 4:1 or 4/1. Another example: in a classroom there are 13 girls and 12 boys. The ratio of girls to boys is 13 to 12 or 13/12 or 1.083 girls for every boy. The ratio of boys to girls is 12/13 or 0.923 boys for every girl. A ratio establishes a relationship between the relative quantities of two or more variables.
