A number has 16 ones, 2 hundreds, and 9 tens. what is the number?

If u add up 16 with 90 it'll give you 106 then add the 200 equals 306

2 hundreds 9 tens and 16 ones ...

16 ones is the same as 1 ten and 6 ones. Add the ten to the other 9 tens and now you have 10 tens.

10 tens is a hundred so add the hundred to the 2 hundreds for a total of 3 hundreds ...

So we are left with 3 hundreds 0 tens and 6 ones ...

306
