    In a group of 20 students, 6 are sixth graders, 2 are seventh graders, and 12 are eighth graders.  Write the ratio of eighth graders to the total number of students in simplest terms.

    Correct Answer
    3:5
    3 to 5
    3/5
    Explanation
    The ratio of eighth graders to the total number of students can be found by dividing the number of eighth graders (12) by the total number of students (20). Simplifying this ratio gives us 3:5, which means that for every 3 eighth graders, there are 5 students in total. Another way to express this ratio is 3 to 5 or 3/5.

    Where should parentheses be placed to make this statement true? 7 + 3 x 5 - 1 = 19

    • A.

      (7 + 3) x 5 - 1 = 19

    • B.

      7 + (3 x 5) - 1 = 19

    • C.

      7 + 3 x (5 - 1) = 19

    • D.

      (7 + 3) x (5 - 1) = 19

    • E.

      The equation does not need parentheses to be true.

    Correct Answer
    C. 7 + 3 x (5 - 1) = 19
    Explanation
    The correct answer is (7 + 3) x (5 - 1) = 19. This is because according to the order of operations in mathematics, parentheses should be used to indicate which operations should be performed first. In this case, the expression inside the first set of parentheses, 7 + 3, should be calculated first. Then, the expression inside the second set of parentheses, 5 - 1, should be calculated. Finally, the multiplication and addition should be performed to get the final result of 19.
