Good Day Girls and Boys,
we are moving on with lesson 2 and that is defining what a RATIONAL NUMBER is and what it is NOT. SO, to begin with you probability have heard this term more as the negative or Irrational if you have ever heard of pi. Pi is a decimal that never ends and it doesn't repeat. Have you heard of pi? It deals with any circles. Anyway, back to Rational Numbers. These are all whole numbers, all fractions and some decimals. The decimals that are rational are the decimals that end or repeat. Such as 3.25 ends therefor it is rational. 8.7^- ( this is supposed to be 8.7 with a bar notation over 7). This is also rational as the 7 repeats and you know what the next digit will be - a 7 and so on. All decimals that do not end or repeat are irrational numbers. So there is no pattern so we don't know the next digit. This is easier than it sounds. The other part of the lesson is ordering fractions, decimals and percents using < > = between the numbers. So if you are comparing 2 fractions, you need common denominators. If you are comparing decimals, line up the decimal point and check. If you are comparing different types of numbers, you must change them into the same- such as all fractions, decimals or percents to compare.
Very wordy I know.
