A negative fraction is a fraction with a negative sign in front of it. Let's show you how to apply negative fractions to equations.

Before learning how solving inequalities works, we need to know what the direction of the inequality symbols mean in the following inequality signs:

Now let's show you how solving inequalities is different from solving equations.

When two fractions have a common denominator, the bottom number of the two fractions are the same. Here are some examples of common denominators:

If two fractions don’t already have a common denominator, you need to see if they have a lowest common denominator (LCD). This allows you to subtract and add fractions.

Here's how to find the lowest common denominator:

Rounding decimals is a simple way to estimate values without having to write countless numbers to the right of the decimal point. You can round decimals to the nearest whole number or the nearest tenth, nearest hundredth, or nearest thousandths decimal. We’ll show you how.

A coordinate plane is a two-dimensional plane with an x-axis (horizontal) and a y-axis (vertical). These axes intersect to form a perpendicular line that separates the coordinate plane into four quadrants.
