Spiegazione passo passo

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

Place value	tens	ones	.	tenths

	1	0	,	7
		0	,	7
-		2	,	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 number to the left (10) which becomes (09) and get (17).

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

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

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

Subtract the numbers in the ones column from the top number:
9-0-2=7

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

Write 0 in the tens place.

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

The solution is: 7,4
