Think of it like this: 36.9=45% times n In order to get n by itself, you must divide 45% by 45% which cancels it out. Then divide 45% by the other side of the equation. The answer would be 82. The number 82 is a happy number. It is also a companion PELL number. And it is the eighth composite number in the 43-aliquot tree.
Roman numerals do not have any symbol occurring consecutively more than three (or sometimes four) times. A number such as 45 000 would be written as the symbol XLV (the Roman numeral for 45) with a horizontal line over the top. The horizontal line indicates the number is multiplied by ten thousand.The remainder of the number would be written as 670 is normally written: DCLXX
you would get a grid that you can plot points on.
45% can be represented as 45/100 or 0.45 You ask yourself if 45/100 is 81, what would be the value for 100/110 (which is 1) and you find that by dividing 81 by 45/100, which is the same as dividing 81 by 0.45 Hence the number is 81/0.45 = 8100/45 = 900/5 = 180
-2/8 or -1/4 would go left of the 0 on the number line
