Q:

I need to know how to do this because I’m bad at math and I have a test tomorrow

Accepted Solution

A:
Answer:I can't see the full question but if there is 364 total students, the answer would be 168.Step-by-step explanation:Suppose that a 6th grade classroom had 6 girls and 7 boys (just like the ratio). This means that for every 6 girls, there are 7 boys. To get the answer, you would put ratio of girls over the ratio of girls + ratio of boys in a fraction. Then multiply it by the total number of students.In this case, that would be 6/13 x 364. The 6 is the ratio of girls, 13 is 6+7 which is the ratio of girls plus the ratio of boys, and 364 is the total number of students in the classroom. When you divide 6/13 then multiply it by 364, you'll get 168. Therefore, there are 168 girls in the classroom. To check if your answer is right, you would subtract the number of girls (that you got) from the total number of students in the class(364-168=196). This would give you the number of boys. Now make those two numbers into a ratio (girls:boys) and simplify. If your ratio simplifiesfrom 168:196 to 6:7, you have the correct answer (168 girls and 196 boys). If it doesn't, you did something wrong so you should go back and double check. REMEMBER:Don't mess up with the ratio. In the question, it says girls to boys is 6:7. Meaning there are 6 girls for every 7 boys. You can't switch that up because otherwise you'll mess up the final answer.
