Welcome back. In this final grammar section, I'm going to show you how you have to write the numbers when you're writing your essay. So let's start off with numbers that are 10 and below. So whenever you have a number that is between the numbers, zero and nine, you have to spell them out, meaning that you have to actually write out the numbers in the English letters. So here's an example of a sentence in its correct version. The sentence reads, it was found that four out of 10 students failed.

Note that here, the number four is less than 10. So for that reason, we have to spell it out. However, if you're talking about the number 10, then you have to write the number in the numeric format. Okay, so we only spell the numbers that are between zero and nine. Now let's look at another example. This time We have an incorrect sentence.

This sentence reads, she has four sisters aged six, 813 and 17. Note that here we have some numbers that are spelled out in the English letters, whereas other numbers are written in the numeric format. So that's why this sentence is incorrect. Because whenever we have a list, it is best to write the numbers numerically. So here's what the correct version of this list would look like. All the numbers that are in the list, six, 813 and 17 have to be written down numerically.

Whereas if a number is not in a list, such as the number four over here, then you have to spell it out in the English letters. Now let's talk about numbers that are 10 and above. In this case, you have to write the numbers that are 10 and above in numerals in the numeric format, okay, the only exception to this rule is if these numbers appear at the start of a sentence. So let's see some examples. Here we have an example where the number 10 or above appears in the middle of a sentence. Note that the number 60 is above 10 and appearing in the middle of a sentence.

In this case, we have to write this number in the numeric format. Let's see another example. In this case, the number 70, which is greater than 10 appears at the beginning of the sentence, and therefore it has to be spelled out in the English letters. But if a number above 10 does not appear at the beginning of a sentence, then we have to write it in the numeric format. Now let's talk about how to write numbers when you're discussing time. Generally speaking, we use numerals to discuss times of the day.

Another point that I want to make about discussing times is that any of these formats for writing am or pm are correct. So you can write em or pm like this. You can also write m and pm like this with the dots in between, or you can write am and pm like this in lowercase letters with the dots, or in just lowercase letters without the dot. All of these are accepted format for writing am and pm. Now, this is how we commonly described time. You can say it starts at five o'clock in the morning.

So when you're talking about five o'clock, you can spell it out in the English letters. Or you can say it starts at 5:35am. In this case, we've used the numeric format. You can also say it starts at 6am. Again, we've used a numeric format here, you can say it starts at 4pm, where you only mentioned the number four, you don't have to add the colon, and 00. To show 4pm.

You can just write a number for now here's an uncommon example. It starts at 435 We usually don't describe time in this way, it's more natural to write for 35 in the numeric format. Now, when it comes to writing, the AM, and pm, all of these different formats are accepted, so feel free to use any of them. Another thing to notice is that in this example, we haven't stated if we're talking about 4:35am, or pm, are we talking about the morning? Or are we talking about evening, so make sure that you're clear about which time you're discussing if you have to describe time in your writing essay. Now let's talk about writing dates.

Dates are typically written in numerals, meaning you have to write them in numeric format. Take note that when we're talking about dates, we do not use the ordinal numbers. ordinal numbers are numbers like first, second, third, fourth, fifth, and so on. We do not use these ordinal numbers when talking about dates. For example, here an incorrect sentence. School begins on September 2 2019.

Notice that here we've used an ordinal number second, and that's why this sentence is incorrect. Here's the correct version of the sentence. School begins on September 2019. Okay, so use the numerals, do not use the ordinal numbers. Now let's talk about how to describe percentages. We write the percentages as numerals as well.

However, if the percentage appears at the beginning of a sentence, then we have to spell it out. So let's see some examples. Here's an example where the percentage appears in the middle of a sentence. In this case, we've written the 63% as a numeral. Here's another example in which the percentage appears at the start of a sentence. In this case, we've spelled out the percentage 80 and one half percent.

Okay, so if it appears at the beginning of the sentence, Then it's best to spell it out. If it appears in the middle of a sentence, then write it in the numeral format. Let's talk about fractions. Now. Generally, we always spell out the simple fractions. And when we're spelling out the simple fractions, we also use hyphens.

Here we have an incorrect version of a sentence. Notice that this is incorrect, because we've written this fraction in the numeric format. To correct this sentence, we have to spell out this fraction. So we have to spell out the fraction in the English letters, and we also have to use a hyphen. Lastly, we're talking about decimals. Whenever you have a decimal, you should write it in the numeric format.

Also, as a general rule, you should try to avoid starting your sentences with the decimals. So let's look at an incorrect example. Here we have an example where we've spelled out zero point 86 as English words. This is Incorrect. The correct way to write decimals is in the numeric format. So we have to write 0.86 in the numeric format.

Now as a final rule, whenever you are in doubt about whether or not you should spell out the number or write it in the numeric format, it's usually best to spell out the numbers in the English letters. So that concludes our video on writing numbers. This was also the last video on our grammar section. In the next video, we're going to be exploring the next ingredient to writing a great essay, which is the lexical resource. In other words, vocabulary
