What is a one-sentence summary of the following article?
The amount box is located on the right side of the check, below the “Date” line and to the right of the “Pay to the Order Of” line. It has a symbol to the left of it indicating the currency — $ or £, for example. In this box, write out the amount of the check you want to write using numbers. Separate the dollar amount and the cent amount with a decimal point — 47.50, for example. You may write a check in which there are no cents to be paid — for example, 47 even dollars. In this, case, you still need to indicate that there are “zero” cents to be paid. You do this by continuing to include the decimal point, but following it with two zeros: 47.00 Underneath the “Pay to the Order Of” line, you will see a second line that has the currency written out at the end of it. In America, for example, this blank line ends with the word “dollars.” On this line, you will write out the amount to be paid in words, rather than numbers. The dollar amount is always written out as words, and the cent amount written as a fraction out of 100. This is because there are 100 cents in a dollar, so if the check amount includes 45 cents, it is 45/100 of a dollar. While this is the basic rule, there are a few different ways to format the actual content of the line.  Written dollar amount + “and” + fractional cent amount: forty-seven and 50/100. Written dollar amount + “dollars and” + fractional cent amount: forty-seven dollars and 50/100. Some people choose to draw a straight horizontal line after the fractional cent amount to fill out the line: forty-seven dollars and 50/100 —————. This prevents other people from adding to or changing the amount you write. Compound numbers do not fall evenly on decades (ten, twenty, thirty), centuries (one hundred, two hundred, etc.) and so on (one million, two billion, etc.) If you have a compound number like 47 (as opposed to 40), you should always place a hyphen between the two parts of the word when writing it out.  Correct: forty-seven Incorrect: forty seven or fortyseven An amount for several hundred, thousand, or even million dollars should still be written out in words on the appropriate line. This might mean you have to write with very small script, so make sure you have enough room.  Correct: two million, five hundred fifty-two thousand, eight hundred forty-seven dollars and 00/100 ——. Incorrect: 2,552,847 dollars and 00/100 ——————.

Summary:
Fill in the “amount” box with a numeric amount. Include the decimal and cent amount even if the amount is in even dollars. Fill in the textual amount. Hyphenate compound numbers. Write out the textual amount even if it is very large.
