There are two nines in 900. Each digit in a number represents a power of 10 based on its position. In the number 900, the first digit represents 9 hundreds, and the second digit represents 0 tens. Therefore, there are two nines in 900.
The 10s and 5s
Well there will be 1 nine for all the 9s in the units column (9, 19, 29 etc.), and 1 nine for all the numbers with 9 in the tens column (90, 91, 92 etc.). So the answer is 20.
6 tens
To calculate 67 tens plus 10 tens, you first convert the tens into their numerical values. This gives you 670 (from 67 tens) plus 100 (from 10 tens), which equals 770. Therefore, 67 tens plus 10 tens equals 770.
