I change 10 ones for 1 ten.
I change 10 ones for 1 ten.
I change 10 tens for 1 hundred.
I change 10 tens for 1 hundred.

Maggie is not correct.
Further explanation:
Given that Mr. House wrote 8 tenths minus 5 hundredths on the board.
Now, Maggie said that the answer is 3 hundredths because 8 minus 5 is equal to 3.
Our aim is to find whether Maggie is correct or not.
From place value chart, 10 tens is equal to 1 hundreds.
Then 3 hundreds is equal to 30 tens and 3 hundreds can be written as follows:
30 tens can be written as follows:
From place value chart it is observed that tenths is greater hundredths.
Tenths are one place after the decimal and hundredths are two places after the decimal.
Eight tenths can be written in the form of decimal as follows:
Five hundredths can be written in the form of decimal as follows:
Now, subtract five hundredths from eight tenths as follows:
Then 8 tenths minus 5 hundredths can be written in the form of hundredths as follows:
Therefore, 8 tenths minus 5 hundredths is equal to 75 hundredths.
From the above explanation we can Maggie is not correct.
Thus, Maggie is not correct.
