What is a Mixed Number?

A mixed number is a combination of a whole number and a fraction. It is written in the form of a b/c, where a is the whole number and b/c is the fraction. For example, 8 1/2 is a mixed number, where 8 is the whole number and 1/2 is the fraction.

Why Convert Mixed Numbers to Improper Fractions?

Converting mixed numbers to improper fractions is an essential skill in mathematics, particularly in algebra and geometry. Improper fractions are easier to work with, especially when performing arithmetic operations such as addition and subtraction. In this article, we will learn how to convert the mixed number 8 1/2 to an improper fraction.

The Formula for Converting Mixed Numbers to Improper Fractions

The formula for converting a mixed number to an improper fraction is:

a b/c = (a × c) + b / c

where a is the whole number, b is the numerator of the fraction, and c is the denominator of the fraction.

Converting 8 1/2 to an Improper Fraction

To convert the mixed number 8 1/2 to an improper fraction, we will use the formula above.

8 1/2 = (8 × 2) + 1 / 2

8 1/2 = 16 + 1 / 2

8 1/2 = 17 / 2

Therefore, the improper fraction equivalent of the mixed number 8 1/2 is 17/2.
