Answer 1

Question 1: The answer would be B) 12:30. If the ratio of girls to boys in the class is 12:18, add both of the numbers to get the total number students in the class. So the ratio would be 12:30

Question 2: The answers would be B) 18/27 and C) 30:45. These two ratios if you were to simplify them, would both equal 6:9.

Question 3: The answer would be C) 9.95. To find the unit price for one cd, you would need to divide $29.85 by 3, which equals $9.95.

Question 4: The answer would be B) 240 words. To find the answer, you need to multiply 34 by 7 to find the amount of words, which is 238 words, but the closest answer to this is B.

Hope this helps!
