Students while writing numbers in words tend to make some common errors. Here is a list of common errors made by students and the ways to avoid them.
Spelling mistakes
Students often make spelling mistakes, so to avoid them, try to memorize them. Some common spelling mistakes like the word thousand could be spelled as thosand, thusand, etc.
Formatting errors
Mixing up numbers and words is also a common mistake. For example one apple and 2 chocolates, instead, we should write 1 apple and 2 chocolates.
Hyphens are used in the wrong way
Hyphens are only used while writing numbers like twenty-two. Make sure that when using hyphens they are used only in numbers like twenty-two or twenty-three
The word ‘and’ is used incorrectly
Depending on whether we are using American English or British English the word ‘and’ is used differently. In American English, we say two hundred ten. In British English, we say two hundred and ten. Children should remember this format.
Pluralizing the numbers.
When writing numbers in words, there is no need to pluralize the numbers like two hundreds or thousands. We just say a thousand or two hundred.
The spelling of the word 27 is twenty-seven.
The number 24 in words is written as twenty-four. This is because 24 has 2 in the tens place and 4 in the ones place.
We would write Rs 22 as twenty-two rupees.
22 + 3 = 25, which is spelled as twenty-five.
22 × 10 = 220. So 220 in words would be two hundred and twenty or two hundred twenties.
