Today, we are going to take a look this question: how to spell 400? At the end of this you will know the correct manner to write down numbers when you are writing.

English rules regarding this matter can be a little confusing. To be perfectly honest, there aren’t any rules in place for how to use digits. In most cases, you can use words, or the digits. We can follow some common sense rules when it comes to numerals, however.

Here are some rules of thumb you can follow when it comes to numerals.

  • Try not to write down numbers bigger than a hundred. According to this rule, we would write 400 as-is, not four hundred.
  • Whenever you’re dealing with decimals, use digits.
  • In the event of two numbers in a row, use digits for the one number and text for the other. This will help your readers to overcome any confusion.
  •  You can write centuries and decades either in text, or with numbers.

Large Sums

Here are some sentences to help you understand what we said above more clearly:

  • The construction of the school cost more than thirty thousand four hundred dollars.

This isn’t correct. Since the cost to build this school is substantial, you should write this down in digits. Otherwise it is only going to create confusion.

  • The consruction of the school cost more than $30,400.

The reader can see the whole amount without having to engage in mental gymnastics because this version is much more accessible.

Decimals

  • Experts project the year-on-year inflation to be nine point five percent.

You should also avoid using this form. Here is the best example:

  • Experts project the year-on-year inflation to be 9.5%.

Centuries & Decades

Let’s take a look at another example, this time with centuries and decades.

  • I can’t believe we used leaded gasoline until the nineties.
  • I can’t believe we used leaded gasoline until the ’90s.

Both of these sentences are correct, you can either spell decades out with words, or use digits.

Money

When you mention money, make sure you either mention the currency sign or its name. Don’t include both of them together.

  • I have $250 dollars in my pocket.

Since you have used the dollar sign, using the word “dollar” again is unnecessary. Either use the word, or the sign. Not both of them.

  • I have $250 in my pocket.
  • I have 250 dollars in my pocket.

Although we mentioned decimals before, when we talk about money it is a bit different. If we are talking about cents, instead of dollars, spell out the whole thing.

  • The bus fare was $0.50, but he had $0.30.
  • The bus fare was fifty cents, but had thirty cents.

Time

In time, writers use both methods.

  • Check the time before you leave, the bus comes at 5:30.
  • Check the time before you leave, the bus comes at half past five.
