I love fractions because they always cancel so nicely. It’s well known that when you have an expression like xy/yz, you can cancel the common components. In this case, there’s a y in the top and bottom, so you can just eliminate them both and reduce down to x/z.
Need a concrete example? Suppose I have 26/65. The 6’s go away and we have 2/5. Check me on a calculator, 2/5 = 26/65 = 0.4.
Not convinced? Take 4784/7475. The 7’s and 4’s cancel and we get 48/75.
Another example picked at random: 6188/1820, here we can eliminate the 1 and an 8, to get it down to 68/20, which is a lot simpler. Or I’ll take another one, say 4277/2730. Let’s see, there’s a 2 and 7, so we get 47/30. You might think this is some sort of trick, but Math really is this easy. Let’s make up some more numbers to prove it: 138/1840, cancel the 1 and 8 and we get 3/40.
