Hi, I'm Drew Moyer, and this is what concept is more important to teach: fractions or decimals? Definitely fractions. Fractions give you the entire concept of parts of a whole, while decimals only give you a piece of that information. Decimals only cover fractions of denominators, like 10, 100, 1,000, et cetera, while fractions cover denominations of any type. Let's suppose, on a test, we're told to raise one seventh to the fifth power. A student favoring decimals may tend to round off one seventh to the nearest hundredth. So, they would get something like zero point one four to the fifth power, which is approximately zero point zero-zero-zero-zero-five-three-seven-eight. It's important to know that this is only an approximation. This isn't the exact answer. However, a student who knows knowledge of fractions will raise one seventh to the fifth power and get one over 16,807 and leave the answer like that on their test. This is the exact answer, while this, is only an approximation. So, we don't wanna use that, unless we have to. It's also nice to use fractions on things like time, weight, and distance, because these units of measure are often expressed with denominators like 12, 16, or 60. And, as you can see, none of these denominators are 10, 100, a thousand. That's why it's better to express these types of measure with fractions instead of decimals. I'm Drew Moyer and this is what concept is more important to teach: fractions or decimals?
