Spiegazione passo passo

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

Place value	tens	ones	.	tenths	hundredths	thousandths

	1	0	,	2	7
-	1	0	,	0	0	4
			,

Put zeros in the blank number places:

Place value	tens	ones	.	tenths	hundredths	thousandths

	1	0	,	2	7	0
-	1	0	,	0	0	4
			,

2. Subtract the numbers using long subtraction method

Because the upper digit (0) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (7) in the next number place which becomes (6) and get (10).

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	1	0	,	2	7	0
-	1	0	,	0	0	4
			,

Subtract the numbers in the thousandths column from the top number:
10-0-4=6

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	1	0	,	2	7	0
-	1	0	,	0	0	4
			,			6

Subtract the numbers in the hundredths column from the top number:
6-0=6

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	1	0	,	2	7	0
-	1	0	,	0	0	4
			,		6	6

Subtract the numbers in the tenths column from the top number:
2-0=2

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	1	0	,	2	7	0
-	1	0	,	0	0	4
			,	2	6	6

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

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	1	0	,	2	7	0
-	1	0	,	0	0	4
		0	,	2	6	6

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

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	1	0	,	2	7	0
-	1	0	,	0	0	4
	0	0	,	2	6	6

The solution is: 0,266
