• hi, am i the first one to post something on this video?
• cool bro
• Can u have fractions like -1/1 or 1.1/1?
• Totally! Fractions are basically a way of representing division. So -1/1 is the same as -1 divided by 1, and 1.1/1 is the same as 1.1 divided by 1. You can even have fractions within fractions. In fact, you can have just about any number inside a fraction. Just keep in mind that 0 doesn't make sense as a denominator (such as 1/0) because it doesn't make sense to divide something into 0 parts. Hope this helps!
• You guys are the best. Thanks for teaching me!
