Midterm Exam Practice Test

Front

What is a fraction?

Back

A fraction represents a part of a whole and is expressed as a ratio of two numbers, the numerator (top number) and the denominator (bottom number). For example, 3/4 means 3 parts out of 4 total parts.

Front

What does the absolute value of a number represent?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, |-2| = 2 and |2| = 2.

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), Quadrant IV (positive x, negative y).

Front

How do you find the distance between two points on a number line?

Back

To find the distance between two points on a number line, subtract the smaller number from the larger number. For example, the distance between -2 and 2 is |2 - (-2)| = 4.

Front

What is the distance between 5/4 and 0?

Back

The distance between 5/4 and 0 is 5/4 or 1.25.

Front

What is the distance between 0 and 4/5?

Back

The distance between 0 and 4/5 is 4/5 or 0.8.

Front

Are the distances between 5/4 and 0 and between 0 and 4/5 the same?

Back

No, the distance between 5/4 and 0 is greater than the distance between 0 and 4/5.

Front

How do you identify a point on a coordinate plane?

Back

A point on a coordinate plane is identified by an ordered pair (x, y), where x is the horizontal position and y is the vertical position.

Front

What is the ordered pair for point C located at (5, 7)?

Back

The ordered pair for point C is (5, 7), meaning it is 5 units right and 7 units up from the origin.

Front

What does it mean for two points to be on the same point on a number line?

Back

Two points are on the same point on a number line if they have the same absolute value, meaning they are equidistant from zero.
