What is four and four ninths as a decimal?

Integers are different from decimal numbers, like 1.6 or 9.4, because they are whole. Integers can also be negative numbers, which may look different depending on the problem that you are solving. For example, if you are asked to add the integers 7 + (-7), the answer will be 0, because the integers cancel one another out.In algebra, the opposite of a whole number is a decimal number.

Because algebraic equations don't deal exclusively with whole numbers, you will often have to solve problems using decimal numbers. In the case of a decimal number, each number to the left of the decimal is a whole number, and those to right are divisible by 10, 100, etc.Like decimals, fractions are individual pieces of a whole that are often expressed like this: 3/4 or 1/8.In this case, the number on the bottom (the denominator) is how many pieces the whole number has been divided into, which in this example is four and eight. The number on the top (the numerator) is how many of those pieces you are dealing with.

In the fractions listed above, you would expect to be dealing with three of the four pieces of a whole number, or one of the eight pieces.
