Fractions may look funky at first, but they're actually really useful once we get the hang of them. The great news is, we're already pros at fractions. We've been thinking about fractions since...

As you can see from the number line, many fractions can have the same value. Different fractions with the same value are called equivalent fractions. Since and share a spot on the number line,...

It would be shocking to find we have a common ancestor with a friend—even more so if it's an enemy. Numerators and denominators know how we feel. If both the numerator and denominator of a fra...

Adding and subtracting fractions can be time-consuming because it often involves a few extra steps. This is a really important and commonly-used skill, though. So let's get to it.Here is .T...

Okay let's be honest, long division with decimals can be very tedious. Also, beyond pre-algebra you probably will rarely, if ever, need to do this without a calculator. Having said that, long d...

In the real world, you will see decimals most often in situations involving money. Pretty much every price tag has a decimal. Let's take a look at some examples here.
