Spiegazione passo passo

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

Place value	tens	ones	.	tenths

	1	1	,	7
		2	,	1
-		4	,	4
			,

2. Subtract the numbers using long subtraction method

Subtract the numbers in the tenths column from the top number:
7-1-4=2

Place value	tens	ones	.	tenths

	1	1	,	7
		2	,	1
-		4	,	4
			,	2

Because the upper digit (1) 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 (11).

Place value	tens	ones	.	tenths
	0	11
	1	1	,	7
		2	,	1
-		4	,	4
			,	2

Subtract the numbers in the ones column from the top number:
11-2-4=5

Place value	tens	ones	.	tenths
	0	11
	1	1	,	7
		2	,	1
-		4	,	4
		5	,	2

Write 0 in the tens place.

Place value	tens	ones	.	tenths
	0	11
	1	1	,	7
		2	,	1
-		4	,	4
	0	5	,	2

The solution is: 5,2
