There are 280.
That looks like it should be the same as 10 times (the number of times the digit 1 occursin the units place in the numbers from 10 to 100), which would work out to 90 .
To find how many sevens there are from 1 to 1000, we can consider the occurrences of the digit '7' in each digit place (hundreds, tens, and units). In the range from 1 to 999, the digit '7' appears 300 times: 100 times in each of the hundreds, tens, and units places. Including the number 1000, which has no sevens, the total remains 300. Thus, there are 300 occurrences of the digit '7' from 1 to 1000.
10 times.. because.. 100 * 10 = 1000
Into 100 five times into 1000 fifty times
90 of them.

10 1000/100 = 10
No. 1000 has 4 digits and is the smallest 4-digit number. The smallest 3-digit number is 100.
10 times.. because.. 100 * 10 = 1000
Into 100 five times into 1000 fifty times
90 of them.
The two-digit factors of 100 and 1000 are all composite.
The digit 9 appears in the units place 100 times from 1 to 1000 (9, 19, 29,..., 989, 999). It also appears in the tens place 100 times (90, 91, 92,..., 99, 190, 191,..., 199, 290,..., 999). Therefore, the digit 9 appears a total of 200 times from 1 to 1000.
10 times for the one's digit, 1-100 10 times for the ten's digit, 60-70 = 20 times
Between 1-100- 11 zero's- ie., 10,20,30,40,.... 100... so 11*10=110
100 times greater.
