In this lesson, you will learn how to compare fractions with different numerators and denominators to the benchmark fraction of one half by using number lines.
Ordering Fractions. We use a number line model to illustrate fraction order for values between 0 and 1. We divide that length into two equal-sized pieces and label the point where the segment is divided with the coordinate. The distance from 0 to represents a length of one-half the whole segment from 0 to 1.
Using Numbers. When using numbers in essays and reports, it is important to decide whether to write the number out in full (two hundred thousand four hundred and six) or to use numerals (200,406). There are some rules to follow to make sure you use numbers in the right way. Use words if the number can be written in two words of fewer.
Prefixes. A prefix is part of a word, at the front. There are prefixes which describe numbers. For example, a hemisphere is half a sphere. There is more than one prefix for each number as they come from different languages (usually Latin or Greek), or they are spelled different ways in different words.
