Sure, I'll match the words or phrases (1-6) with their corresponding definitions (A-F):

1. Point - F) a dot that is placed after a whole unit in a decimal number.

   • In mathematics, a point, specifically in the context of decimal numbers, refers to the decimal point. It is the dot used to separate the whole part of a number from its fractional part. For example, in the number 23.45, the decimal point separates the whole number 23 from the fractional part 45.

2. Reduce - B) to change to a form with the lowest possible numbers.

   • To reduce in mathematics often refers to simplifying a fraction. It means converting the fraction to its simplest form, where the numerator and denominator are as small as possible but still retain the same value. For example, reducing the fraction 8/16 would result in 1/2.

3. Out of - E) describing the ratio between actual and potential amounts.

   • "Out of" is a term used to describe a ratio or a fraction, indicating a comparison between a part and a whole. For instance, if you have 3 apples out of a total of 5, it means you have 3/5 of the total apples.

4. Quantity - A) any numerical value.

   • Quantity refers to any numerical value, representing an amount, number, or magnitude. It's a general term in mathematics that can refer to a whole number, a fraction, a decimal, or any other numerical expression.

5. Mixed Number - D) an amount that is expressed as a whole number and a fraction.

   • A mixed number is a number that combines a whole number with a fraction. It's used to express amounts that are more than one but not a whole number. For example, 2 3/4 is a mixed number, with 2 being the whole number and 3/4 being the fraction.

6. Improper Fraction - C) an amount that is greater than one and expressed as a fraction.

   • An improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number). This type of fraction represents a quantity greater than one. For example, 9/4 is an improper fraction.

Each term is closely related to basic concepts in mathematics, particularly in the areas of arithmetic and fractions. Understanding these concepts is fundamental to mastering more complex mathematical operations and theories.
