Spiegazione passo passo

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

Place value	ones	.	tenths

	4	,	7
	0	,	7
-	1	,	6
		,

2. Subtract the numbers using long subtraction method

Because the upper digit (7) in the tenths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (17).

Place value	ones	.	tenths
	3		17
	4	,	7
	0	,	7
-	1	,	6
		,

Subtract the numbers in the tenths column from the top number:
17-7-6=4

Place value	ones	.	tenths
	3		17
	4	,	7
	0	,	7
-	1	,	6
		,	4

Subtract the numbers in the ones column from the top number:
3-0-1=2

Place value	ones	.	tenths
	3		17
	4	,	7
	0	,	7
-	1	,	6
	2	,	4

The solution is: 2,4
