Put zeros in the blank number places:

Place value	hundreds	tens	ones	.	tenths	hundredths

	1	1	2	.	2	5
-		2	4	.	0	0
				.

Subtract the numbers in the hundredths column from the top number:
5-0=5

Place value	hundreds	tens	ones	.	tenths	hundredths

	1	1	2	.	2	5
-		2	4	.	0	0
				.		5

Subtract the numbers in the tenths column from the top number:
2-0=2

Place value	hundreds	tens	ones	.	tenths	hundredths

	1	1	2	.	2	5
-		2	4	.	0	0
				.	2	5

Because the upper digit (2) in the ones column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (12).

Place value	hundreds	tens	ones	.	tenths	hundredths
		0	12
	1	1	2	.	2	5
-		2	4	.	0	0
				.	2	5

Subtract the numbers in the ones column from the top number:
12-4=8

Place value	hundreds	tens	ones	.	tenths	hundredths
		0	12
	1	1	2	.	2	5
-		2	4	.	0	0
			8	.	2	5

Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (10).

Subtract the numbers in the tens column from the top number:
10-2=8

Write 0 in the hundreds place.

The solution is: 88.25
