The following are examples of mixed decimals, their

equivalent mixed numbers, and how they are read:

A decimal is any number written with a decimal

point, which includes decimal fractions and mixed

decimals. For the rest of the manual, we will refer to

decimal fractions and mixed decimals as decimals.

Therefore, -7/32 = -0.21875.

From our study of fractions, it should be clear that

Example: Convert 51/8 to a decimal.

Solution:

Writing the same values as decimals would be

equivalent to

0.5 = 0.50 = 0.500

In other words, the value of a decimal is not

changed by attaching zeros to the right of any decimal

point after the last digit.

One way to convert a fraction to a decimal is to

Example: Convert l/3 to a decimal.

Example: Convert 3/5 to a decimal.

Solution:

Solution:

So the answer is 3/5 = 0.6. Notice that the decimal point
