Spiegazione passo passo

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths

	0	,	5
-	0	,	4	7	7	2
		,

Put zeros in the blank number places:

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths

	0	,	5	0	0	0
-	0	,	4	7	7	2
		,

2. Subtract the numbers using long subtraction method

Because the upper digit (0) in the ten thousandths column is too small to get a positive difference, borrow 1 from the number to the left (500) which becomes (499) and get (10).

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
			4	9	9	10
	0	,	5	0	0	0
-	0	,	4	7	7	2
		,

Subtract the numbers in the ten thousandths column from the top number:
10-0-2=8

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
			4	9	9	10
	0	,	5	0	0	0
-	0	,	4	7	7	2
		,				8

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
			4	9	9	10
	0	,	5	0	0	0
-	0	,	4	7	7	2
		,			2	8

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
			4	9	9	10
	0	,	5	0	0	0
-	0	,	4	7	7	2
		,		2	2	8

Subtract the numbers in the tenths column from the top number:
4-4=0

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
			4	9	9	10
	0	,	5	0	0	0
-	0	,	4	7	7	2
		,	0	2	2	8

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
			4	9	9	10
	0	,	5	0	0	0
-	0	,	4	7	7	2
	0	,	0	2	2	8

The solution is: 0,0228
