Step-by-step explanation

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

Place value	ones	.	tenths

	6	.	2
	3	.	2
-	1	.	7
		.

2. Subtract the numbers using long subtraction method

Because the upper digit (2) in the tenths column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (12).

Place value	ones	.	tenths
	5		12
	6	.	2
	3	.	2
-	1	.	7
		.

Subtract the numbers in the tenths column from the top number:
12-2-7=3

Place value	ones	.	tenths
	5		12
	6	.	2
	3	.	2
-	1	.	7
		.	3

Subtract the numbers in the ones column from the top number:
5-3-1=1

Place value	ones	.	tenths
	5		12
	6	.	2
	3	.	2
-	1	.	7
	1	.	3

The solution is: 1.3
