Explanation
The fraction 4/1 represents a quarter because when you divide 4 by 1, the result is 4, which means there are 4 equal parts. Since a quarter is one of those equal parts, the fraction 4/1 represents a quarter.

Explanation
When rounding a number to the nearest whole number, we look at the digit immediately to the right of the decimal point. If this digit is 5 or greater, we round up by adding 1 to the whole number. In this case, the digit to the right of the decimal point is 2, which is less than 5. Therefore, we do not round up and the nearest whole number to 6.5217 is 6.

Explanation
The addends in the equation 2+4=6 are 2 and 4.

Explanation
In an addition problem, the numbers that are added together are called addends. The addends are the individual numbers being combined to find the total sum or the result of the addition problem.

Explanation
The symbol that separates dollars from cents in money is the decimal point. This is because the decimal point is used to indicate the division between the whole dollar amount and the fractional cent amount in a monetary value.

Explanation
A time line is an ordered list of historic moments that represents events in chronological order. It provides a visual representation of the sequence of events, allowing individuals to understand the progression of history and the relationships between different events. Unlike a calendar, which primarily focuses on dates and months, a time line emphasizes the specific moments or events that occurred throughout history. Therefore, a time line is the most appropriate option for an ordered list of historic moments.

Explanation
A tenth is one of ten equal parts because when something is divided into ten equal parts, each part represents one-tenth of the whole. Therefore, a tenth is the correct answer.

Explanation
A tally table is a table that uses tally marks to record data. Tally marks are a simple and efficient way to keep track of quantities by making vertical marks. They are commonly used for counting and recording data in various fields such as statistics, surveys, and inventories. The other options mentioned (Kitchen Table, Wood Table, Desk) are types of furniture and do not involve the use of tally marks for recording data.

Explanation
The term "compare" refers to the act of evaluating two numbers to determine if they are equal, less than, or greater than each other. It involves comparing the values of the numbers and analyzing their relationship in terms of magnitude. Multiplication, addition, and subtraction are mathematical operations that can be used to perform calculations on numbers, but they do not directly indicate whether numbers are equal to, less than, or greater than each other.

Explanation
The term for facts where the addends are the same number, such as 2 + 2, is doubles. In this case, both addends are 2, making it a double.

Explanation
An estimate is a number close to an exact amount. It is an approximation or a rough calculation that is used when an exact value is not known or not necessary.

Explanation
A plane is a flat surface that extends infinitely in all directions. Unlike a sphere, which is a three-dimensional object, a plane has no thickness and is two-dimensional. A board and a cube are also three-dimensional objects and do not fit the description of a flat surface that extends infinitely. Therefore, the correct answer is plane.

Explanation
A closed plane figure with straight lines is called a polygon. A polygon is a two-dimensional shape that is formed by connecting straight line segments. It has straight sides and angles, and all its vertices lie on the same plane. Examples of polygons include triangles, squares, rectangles, pentagons, and hexagons. A circle, on the other hand, is a curved shape and does not have straight lines. Radius is a measurement used to describe the distance from the center of a circle to any point on its circumference. A cylinder is a three-dimensional shape and is not a closed plane figure with straight lines.

Explanation
The correct answer is P.M. P.M. stands for post meridiem, which refers to the time period between noon and midnight. It is used to differentiate between the morning hours (A.M.) and the afternoon and evening hours (P.M.). Therefore, P.M. designates the hours between noon and midnight.

Explanation
The factors in the problem 2 x 8 = 16 are 2 and 8. This means that 2 and 8 are the two numbers that, when multiplied together, result in the product of 16.
