13 x 10 = 130
90 x 1 = 90
130 + 90 = 220
220/100 = 2.2

13 tens=130, 13 ones=13. 130+13=143
Because when there is one ten you have to put it in the other place value
2 tens and 13 ones add up to 33 because 10 +10 +13 = 33.

The number you mentioned, 13 hundreds, 6 tens, 3 ones, 5 tenths, and 5 hundredths, can be written as 1,363.55.
13 tens=130, 13 ones=13. 130+13=143
Because when there is one ten you have to put it in the other place value
205,645 I think.
You can't subtract 15 ones from 15 tens. The bills are all tens, so you'd have to get change first. Then you'd be subtracting 15 ones from 13 tens and 20 ones, or from 13 tens, one 5, and 15 ones.
2 tens and 13 ones add up to 33 because 10 +10 +13 = 33.
The answer is 63. This is because 5 tens = 50 and 13 ones is 13. Then, add 50 and 13, and you get 63.
you write it like this:13.0 because even though there's a number in the ones spot since there is a number in the tens spot it makes it 13 tens
