(9+5+5+1+1) x 1
Working on the .21 only. There are 2 digits in 21. The 1 is in the 100th decimal place.So .21 is also 21/100 which gives a final answer of 6 21/100

One possible solution is: 4.4 + 4 / .4 = 21
To create the numbers 1-100 using the digits 2, 0, 1, and 2, you can use various combinations and operations. For example, you can form numbers like 1 (by using 2-2+1), 2 (using one of the 2s), 10 (by combining 2 and 0), and higher numbers such as 20 or 21. By creatively using addition, subtraction, and combinations of the digits, you can generate many numbers up to 100. However, some numbers may not be possible with the given digits and operations.
You can make: 1 combination containing 0 digits, 7 combinations containing 1 digits, 21 combinations containing 2 digits, 35 combinations containing 3 digits, 35 combinations containing 4 digits, 21 combinations containing 5 digits, 7 combinations containing 6 digits, and 1 combinations containing 7 digits. That makes 2^7 = 128 in all.
Try the different numbers - there are only 11 after all - and multiply their digits. Or analyze the factors of the number 21.
Any number using each of the digits once will be a multiple of 3: eg 1597864302
42/40 = 21/20 or 11/20

To get 900 using the digits 1 to 9 without repetition, you can multiply 9 by 100. This is because 9 times 100 equals 900. By using the digit 9 once and the digit 1 twice, you can achieve the desired result without repeating any digits.
21
There are 9 pages with a single digit (pages 1-9) = 9 digits There are 30 - 9 = 21 pages with two digits = 21 × 2 = 42 digits → There are 9 + 41 = 51 digits in total.
You can abbreviate the year in a formal document by using the last two digits of the year preceded by an apostrophe, such as '21 for the year 2021.
2+3=5... 5x4=20... 20+1=21 !
