What is 2 as a fraction?

2 can be expressed as a fraction in multiple ways, including:

• 2/1: This is a proper fraction because the numerator (2) is less than the denominator (1). It can also be written as a mixed number, 2 1/1.
• 4/2: This is an improper fraction because the numerator (4) is greater than the denominator (2). It can also be simplified to 2, which is a whole number.
• 10/5: This is also an improper fraction because the numerator (10) is greater than the denominator (5). It can be simplified to 2, which is a whole number.

In general, any whole number can be expressed as a fraction by placing it over a denominator of 1 (e.g. 5/1, 10/1, etc.).
