    How do you write 40/100 as a decimal?

    • 0.0004

    • 4

    • 40

    • 0.4

    Correct Answer
    A. 0.4
    Explanation
    To write a fraction as a decimal, you divide the numerator (top number) by the denominator (bottom number). In this case, 40 divided by 100 equals 0.4. Therefore, the decimal representation of 40/100 is 0.4.

    Rate this question:

  • 3. 

    What is the place value of the 3 in 0.3?

    • Hundredths Place

    • Tenths Place

    • Thousandths Place

    • Ten Thousandths Place

    Correct Answer
    A. Tenths Place
    Explanation
    In the decimal number system, the place value of a digit determines its position in relation to the decimal point. The digit 3 in 0.3 is located after the decimal point, which means it is in the tenths place. The tenths place represents one-tenth of a whole unit.

    Rate this question:

  • 4. 

    What does 0.6 + 7.49 equal?

    • 8.390000000000001

    • 1.49

    • 8.09

    • 8.6

    Correct Answer
    A. 8.09
    Explanation
    0.6 + 7.49 equals 8.09. This can be calculated by adding the two numbers together.

    Rate this question:

  • 5. 

    What is 0.8 + 0.55?

    • 1.25

    • 1.36

    • 1.35

    • 1.45

    Correct Answer
    A. 1.35
    Explanation
    The correct answer is 1.35 because when you add 0.8 and 0.55, you get a sum of 1.35.

    Rate this question:

  • 6. 

    What is the median of 1, 3, 5, 7, 9?

    • 3

    • 3 to 7

    • 7

    • 5

    Correct Answer
    A. 5
    Explanation
    The median is the middle value in a set of numbers when they are arranged in ascending order. In this case, the numbers are already in ascending order: 1, 3, 5, 7, 9. The middle value is 5, so it is the median.

    Rate this question:

  • 7. 

    If all three sides of a triangle are 4 inches long, what kind of triangle is it?

    • Scalene Triangle

    • Isosceles Triangle

    • Equilateral Triangle

    • Right Triangle

    Correct Answer
    A. Equilateral Triangle
    Explanation
    An equilateral triangle is a type of triangle where all three sides are equal in length. In this case, since all three sides of the triangle are 4 inches long, it can be concluded that it is an equilateral triangle.

    Rate this question:

  • 8. 

    What is the least common denominator of 2/3 and 5/6?

    • 3

    • 18

    • 6

    • 12

    Correct Answer
    A. 6
    Explanation
    The least common denominator is the smallest multiple that both denominators (3 and 6) can evenly divide into. In this case, the least common denominator is 6 because both 3 and 6 can evenly divide into 6. This means that if we convert 2/3 and 5/6 to fractions with a denominator of 6, we can compare them more easily.

    Rate this question:

  • 9. 

    Which number is to the left of -3 on the number line?

    • -4

    • 0

    • -1

    • 3

    Correct Answer
    A. -4
    Explanation
    The number to the left of -3 on the number line is -4. This is because -4 is a smaller number than -3 and is located to the left of -3 on the number line.

    Rate this question:

  • 10. 

    What is the coordinate of the origin?

    • (0, 0)

    • (3, 3)

    • (2, 2)

    • (1, 1)

    Correct Answer
    A. (0, 0)
    Explanation
    The coordinate of the origin is (0, 0) because the origin is defined as the point where the x-axis and y-axis intersect, and at this point, both x and y coordinates are zero.

    Rate this question:

  • 11. 

    What is 1/4 + 1/2?

    • 6-Feb

    • 8-Mar

    • 2-Feb

    • 4-Mar

    Correct Answer
    A. 4-Mar
    Explanation
    The given question asks for the sum of 1/4 and 1/2. To find the answer, we need to find a common denominator, which in this case is 4. When we convert 1/2 to have a denominator of 4, it becomes 2/4. Now, we can add 1/4 and 2/4, which gives us a total of 3/4. Therefore, the correct answer is 4-Mar.

    Rate this question:

  • 12. 

    What is 10 + 25 / 5?

    • 7

    • 40

    • 15

    • 27

    Correct Answer
    A. 15
    Explanation
    The correct answer is 15 because the order of operations dictates that we should perform division before addition. So, 25 divided by 5 equals 5, and then we add 10 to get a total of 15.

    Rate this question:

  • 13. 

    If two lines are perpendicular, what could their slopes be?

    • -1/9 And -9

    • 1/9 And -1/9

    • 1/9 And -9

    • 1/9 And 9/1

    Correct Answer
    A. 1/9 And -9
    Explanation
    If two lines are perpendicular, their slopes are negative reciprocals of each other. The slope of the first line is 1/9, and the slope of the second line is -9. Since -9 is the negative reciprocal of 1/9, these slopes satisfy the condition for perpendicular lines.

    Rate this question:

  • 14. 

    What is the complement of a 41 degree acute angle?

    • 49 Degrees

    • 131 Degrees

    • 4 Degrees

    • 41 Degrees

    Correct Answer
    A. 49 Degrees
    Explanation
    The complement of an acute angle is the angle that, when added to the given angle, equals 90 degrees. Since the given angle is 41 degrees, the complement can be found by subtracting 41 from 90, which equals 49 degrees. Therefore, the correct answer is 49 degrees.

    Rate this question:

  • 15. 

    What is the median of 2, 4, 6, 8, 10, 12?

    • 8

    • 6 To 8

    • 7

    • 6

    Correct Answer
    A. 7
    Explanation
    The median is the middle value when the numbers are arranged in ascending order. In this case, when the numbers 2, 4, 6, 8, 10, 12 are arranged in ascending order, the middle value is 8. However, since there is an even number of values, there are two middle values, which are 6 and 8. To find the median of the given numbers, we take the average of these two middle values, which is 7.
