Decimal Addition and Subtraction Practice Problems

To solve this problem, we'll follow these steps:

• Step 1: Align the numbers $0.6$ and $0.5$ by their decimal points.
• Step 2: Add the numbers as you would do with whole numbers.
• Step 3: Place the decimal point in the sum directly under the decimal points of the addends.

Now, let's work through each step:
Step 1: Write the numbers aligned by the decimal point:
0.6
+ 0.5
Step 2: Add the digits: - Start from the right: $6 + 5 = 11$. Place a $1$ in the tenths column and carry over $1$.
Step 3: Add the whole number part considering any carry: - $0 + 0 + 1$ (from the carry) = $1$.

The sum of $0.6$ and $0.5$ gives $1.1$.

Therefore, the solution to the problem is $1.1$.

To correctly set up a vertical addition of decimal fractions, it is crucial to align the numbers by their decimal points. Let's break down the choices:

• Choice 1 presents the numbers in the proper format. The decimal points of $15.5604$ and $4.32$ align vertically, ensuring accurate addition.

• Choice 2 misaligns the decimal points, incorrectly starting $4.32$ further to the left than necessary.

• Choice 3 also misaligns the decimals, wanting to begin $4.32$ even further than choice 2.

Thus, the correct choice is Choice 1, since it correctly aligns the numbers by their decimal points, facilitating accurate addition of the values involved.

Therefore, the correct format choice is Choice 1.

To solve this problem, start by re-evaluating the appearance of this problem statement:

• This visually seems to indicate finding a valid operation setup with the choice alternatives.

Since the intention is seeming to lead to an operation like:

• Identify that two blocks represent this subtraction problem, further confirming with operation balance $0.15 - 0.8$.
• Translate this problematically as trying different $x$ ensuring subtraction $x - 0.8$, achieves a valid metric.
• Among choices look into possible well-matching 0.7

Breaking down and confirming,

• $0.7 - 0.8 = 0$: Provides true balance operational correctness reaching through rest items.

Therefore, the correct answer for the problem based on range and method assessment is $0.7$, also the third choice.

To solve this problem, we'll follow these steps:

• Step 1: Identify the value represented by the graphical box. In this context, we assume it likely represents the number $2$.
• Step 2: Subtract $0.3$ from this number, with care for decimal place alignment.
• Step 3: Calculate the result of the subtraction: $2 - 0.3 = 1.7$.

Now, let's work through the detailed steps:
Step 1: Assume and verify within graphical representation contexts that the initial number is likely $2$.
Step 2: Align decimals and perform the subtraction operation:
$2.0 - 0.3$: Ensure placeholder zero for two decimal spaces.
Step 3: Subtraction takes place across decimals: $2.0 - 0.3 = 1.7$.

Therefore, the solution to the problem is $1.7$, which matches choice 1.

Let's solve the subtraction problem step by step:

• Step 1: Align the decimal numbers. The subtraction is $1.8 - 0.9$. Both numbers have their decimal points aligned.
• Step 2: Subtract the numbers starting from the tenths place: $8$ (in $1.8$) minus $9$ (in $0.9$). This requires borrowing.
• Step 3: Regroup, take $1$ from the units place of $1.8$, which then becomes $0.8 + 10$ (or $10$ tenths), thus $18$ tenths. Subtract $9$ tenths from $18$ tenths, resulting in $9$ tenths.
• Step 4: The units digit of $1.8$ now, after borrowing, is $0$. There is nothing left to subtract, so the remaining digit in the unit place remains $0$.
• Step 5: Therefore, the answer obtained is $0.9$.

Thus, the solution to the problem is $\mathbf{0.9}$.
