12.2-9.1
The result of subtracting 9.1 from 12.2 is 3.1.
To subtract 9.1 from 12.2, follow these steps:
Step 1: Align the numbers vertically, with the decimal points lined up:
12.2
- 9.1
Step 2: Subtract the numbers in the ones place (rightmost place):
12.2
- 9.1
= 3.1
Step 3: Since the number being subtracted (9.1) is smaller than the number it's being subtracted from (12.2), we can move to the decimal places:
12.2
- 9.1
= 3.1
Step 4: Subtract the numbers in the tenths place (the first digit after the decimal point):
12.2
- 9.1
= 3.1
Step 5: The final result is 3.1, which is the difference between 12.2 and 9.1.
To subtract two numbers, such as 12.2 - 9.1, you can follow these steps:
Step 1: Place the larger number (in this case, 12.2) on top and the smaller number (9.1) below it.
```
12.2
- 9.1
```
Step 2: Align the decimal points of both numbers.
```
12.2
- 9.1
```
Step 3: Subtract the numbers vertically, starting with the ones place and moving leftwards.
First, subtract the ones place: 2 - 1 = 1. Write the result under the line.
```
12.2
- 9.1
1
```
Step 4: Continue subtracting the decimal places.
Since there are no more decimal places in the smaller number (9.1), we can write zeros in their place:
```
12.2
- 9.1
1.0
```
Step 5: Finally, subtract the tenths place: 1 - 9 = -8. Write the result under the line.
```
12.2
- 9.1
1.0
-8.0
```
The result of 12.2 - 9.1 is 3.1.
