118 The following from rjsiekman; Think of it as the number of times the 3 will be written in the hundreds, tens, and ones column. This analysis assumes whole numbers; otherwise you can write a 3 an infinite number of times.
In the hundreds, 301.....399 is 99 (because it is stated the numbers between 300 & 400; 300 is not included). In the tens, 3 will be written for 330....339 which adds another 10. In the ones, 3 will be written for 303, 313....393 which adds another 10. So, in total, the 3 will be written 119 times.
Between 200 and 400 there are 18 whole numbers that contain the digit 7 once and only once: 207, 217, 227, 237, 247, 257, 267, 287, 297, 307, 317, 327, 337, 347, 357, 367, 387, and 397.
234, 243, 324, 342, 423, and 432.
100000
1,000,000 that's how you write 1 milion in numbers!
N={3,4,5,6,7,8}
If you write all of the counting numbers from 200 to 400,you will write the digit ' 5 ' forty times.
The digit 3 will be written 20 times.
120 times.
18 times
Very interesting !No.In all of the 3-digit numbers ... 100 - 999 ... each of the digits 1 - 9 appears 190 times,but zero appears 990 times.

write an addition story for two 3-digit numbers. write the answer to your story
Write "0.8", followed by any digit or digits. Include at least one non-zero digit.
You write out the numbers. If you just simply put the digit on the paper it will be incorrect.
20, don't forget 90, 91, 92, 93 ...... etc
Write them as decimals, and compare. If the first digit of two numbers is equal, compare the second digit; if the second digit is equal, compare the third digit, etc.
Generally speaking, when writing out numbers in words between 21 and 99 in English, hyphens are used between the tens digit and units digit. This contrasts with a language such as Italian, where numbers between 21 and 99 are written as single words, without hyphens, for example, the word for the number 32 is trentadue.
