What symbol separates the whole number part from the fractional part in a decimal?

Decimal point. The decimal point is the standard symbol used in mathematics to separate the whole number part from the fractional part of a decimal number.

Which of these is an example of a terminating decimal?

0.25. A terminating decimal is a decimal number that ends after a finite number of digits, such as 0.25, unlike repeating or non-terminating decimals.

What is the decimal expansion of a repeating decimal like 0.333...?

A digit repeats infinitely. A repeating decimal is defined as a decimal number in which a digit or a group of digits repeats infinitely, such as 0.333...

Which of these is an example of an irrational number?

π. An irrational number cannot be expressed as a fraction and has a non-repeating, non-terminating decimal expansion, with pi being a classic example.

In the number 3.45, what does the 4 represent?

Tenths. The place value of a digit to the right of the decimal point starts with tenths, followed by hundredths, then thousandths, and so on.

What is the result of multiplying 2.5 by 100?

250. Multiplying a decimal by a power of 10 moves the decimal point to the right by the number of zeros; 2.5 times 100 equals 250.

How would you write 0.25 as a fraction?

25/100. To convert a decimal to a fraction, you count the decimal places and use a power of 10 as the denominator, so 0.25 becomes 25/100.

Which of these is a common real-life example of using decimals?

Money. Money is a common real-life example of decimals, where the dollar is the whole number and the cents represent the fractional part of the total.

What type of number has a decimal expansion that terminates or repeats?

Rational number. Rational numbers are defined as numbers that can be written as a fraction of two integers and have decimal expansions that either terminate or repeat.

What is often used to express very large or small numbers using powers of 10?

Scientific notation. Scientific notation is a method used to express very large or very small numbers by combining decimal notation with powers of 10.

In Grade 8, students learn that every number has a decimal expansion that is either terminating, repeating, or non-repeating and non-terminating.
A terminating decimal is a decimal number that ends after a finite number of digits, such as 0.25 or 3.7.

An irrational number is a number that cannot be expressed as a fraction and has a non-repeating, non-terminating decimal expansion, such as π or √2.
The place value of a digit in a decimal number is determined by its position relative to the decimal point, with positions to the right being tenths, hundredths, thousandths, and so on.
To convert a decimal to a fraction, count the number of decimal places and use a power of 10 as the denominator (e.g., 0.25 = 25/100).
