To solve this problem, we'll follow these steps:
Step 1: Align the decimal numbers by their decimal points: , , and .
Step 2: Perform the addition column by column, starting from the rightmost side.
Step 3: Sum the values, taking care of decimal alignment.
Now, let's work through each step:
Step 1: Prepare the addition by aligning the decimal points:
13.4
+ 4.5
+ 0.1
Step 2: Start from the rightmost digits (tenths place):
Step 3: Now, add the whole number places:
Add these results together:
Therefore, the solution to the problem is .
18
\( \text{0.6+0}.5= \)
Decimal points must be aligned vertically so that digits in the same place value (ones, tenths, hundredths) are added together correctly. Without alignment, you're adding different place values!
That's fine! In this problem, 13.4 and 4.5 have one decimal place while 0.1 also has one. Just imagine invisible zeros if needed: 13.40, 4.50, 0.10.
When 0.4 + 0.5 + 0.1 = 1.0, you get 1 whole number and 0 tenths. Write down 0 in the tenths place and carry the 1 to add with the ones column.
Both are correct! and represent the same value. Since there are no remaining decimal parts, we can write it as the whole number 18.
Yes! Addition is commutative, so 13.4 + 4.5 + 0.1 = 4.5 + 13.4 + 0.1. The answer will always be the same regardless of order.
