Grade 5 Math Worksheets: Adding decimals in columns | Worsheets library - Free Printable

I will solve the problem by adding the decimals in columns as instructed. I'll go through each of the 15 problems one by one, aligning the decimal points and performing the addition.

Let me start with problem 1: 6.048 + 8.854

First, I'll align the decimal points:
```
6.048
+ 8.854
-------
```

Adding from right to left:
- Thousandths place: 8 + 4 = 12, write down 2, carry 1
- Hundredths place: 4 + 5 + 1 (carry) = 10, write down 0, carry 1
- Tenths place: 0 + 8 + 1 (carry) = 9, write down 9
- Units place: 6 + 8 = 14, write down 14

So, 6.048 + 8.854 = 14.902

Now, let me solve problem 2: 35.38 + 59.94

Aligning the decimal points:
```
35.38
+ 59.94
-------
```

Adding from right to left:
- Hundredths place: 8 + 4 = 12, write down 2, carry 1
- Tenths place: 3 + 9 + 1 (carry) = 13, write down 3, carry 1
- Units place: 5 + 9 + 1 (carry) = 15, write down 5, carry 1
- Tens place: 3 + 5 + 1 (carry) = 9, write down 9

So, 35.38 + 59.94 = 95.32

Problem 3: 81.88 + 81.66

Aligning the decimal points:
```
81.88
+ 81.66
-------
```

Adding from right to left:
- Hundredths place: 8 + 6 = 14, write down 4, carry 1
- Tenths place: 8 + 6 + 1 (carry) = 15, write down 5, carry 1
- Units place: 1 + 1 + 1 (carry) = 3, write down 3
- Tens place: 8 + 8 = 16, write down 16

So, 81.88 + 81.66 = 163.54

Problem 4: 31.01 + 46.60

Aligning the decimal points:
```
31.01
+ 46.60
-------
```

Adding from right to left:
- Hundredths place: 1 + 0 = 1, write down 1
- Tenths place: 0 + 6 = 6, write down 6
- Units place: 1 + 6 = 7, write down 7
- Tens place: 3 + 4 = 7, write down 7

So, 31.01 + 46.60 = 77.61

Problem 5: 32.91 + 34.08

Aligning the decimal points:
```
32.91
+ 34.08
-------
```

Adding from right to left:
