How many times does 1to50 2?
To clarify your question: If you're asking how many times the number 2 can be counted from 1 to 50, here’s the breakdown: The number 2 appears in the following sequence as a single digit: 2, 12, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 32, 42. In the number 22, the digit 2 appears twice. Let's count the occurrences: In the range 1 to 9, 2 appears once. In the range 10 to 19, 2 appears once (12). In the range 20 to 29, 2 appears 11 times (20, 21, 22 twice, 23, 24, 25, 26, 27, 28, 29). In the range 30 to 39, 2 appears once (32). In the range 40 to 49, 2 appears once (42). In the range 50, 2 does not appear. Summing these, the total number of times the digit 2 appears from 1 to 50 is: 1 (from 1-9) + 1 (from 10-19) + 11 (from 20-29) + 1 (from 30-39) + 1 (from 40-49) = 15 times. So, the digit 2 appears 15 times in the numbers from 1 to 50.
