Spiegazione passo passo

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

Place value	ones	.	tenths

	2	,	2
-	0	,	6
		,

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 (2) in the next number place which becomes (1) and get (12).

Place value	ones	.	tenths
	1		12
	2	,	2
-	0	,	6
		,

Subtract the numbers in the tenths column from the top number:
12-6=6

Place value	ones	.	tenths
	1		12
	2	,	2
-	0	,	6
		,	6

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

Place value	ones	.	tenths
	1		12
	2	,	2
-	0	,	6
	1	,	6

The solution is: 1,6
