Step-by-step explanation

1. Rewrite the numbers from top to bottom, aligned by their place values

Place value	tens	ones	.	tenths

	2	2	.	3
-	1	0	.	7
			.

2. Subtract the numbers using long subtraction method

Because the upper digit (3) in the tenths column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (13).

Place value	tens	ones	.	tenths
		1		13
	2	2	.	3
-	1	0	.	7
			.

Subtract the numbers in the tenths column from the top number:
13-7=6

Place value	tens	ones	.	tenths
		1		13
	2	2	.	3
-	1	0	.	7
			.	6

Subtract the numbers in the ones column from the top number:
1-0=1

Place value	tens	ones	.	tenths
		1		13
	2	2	.	3
-	1	0	.	7
		1	.	6

Subtract the numbers in the tens column from the top number:
2-1=1

Place value	tens	ones	.	tenths
		1		13
	2	2	.	3
-	1	0	.	7
	1	1	.	6

The solution is: 11.6
