Decimal Multiplication Division by 10 100 1000 Practice

To solve the problem $0.07 \times 10$, we recognize that multiplying a decimal number by 10 involves shifting the decimal point one place to the right.

Let's work through the steps:

• Initially, the decimal number $0.07$ has a decimal point located between the "0" in the tenths place and "07".
• When multiplying by 10, we shift the decimal point one place to the right. This changes the number from $0.07$ to $0.7$.

The decimal point's new position results in the number $0.7$, representing the product of the original number and 10.

The solution to the problem is $0.7$.

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

• Step 1: Understand the operation needed: multiply the decimal 0.3 by 10.
• Step 2: Apply the rule for multiplying by powers of 10.
• Step 3: Execute the operation and write down the result.

Now, let's work through each step:
Step 1: We need to multiply 0.3 by 10. Multiplying by 10 involves shifting the decimal point.
Step 2: Using the rule for multiplying decimals by 10, we shift the decimal point in 0.3 one place to the right.
Step 3: Originally, the decimal point in 0.3 is after the '3'. After shifting it right by one place, we get '3.0'. This is equivalent to $3$.

Therefore, the solution to the problem is $3$.

To solve this division problem, we will follow these steps:

• Step 1: Identify the initial position of the decimal point in the number $12.2$.
• Step 2: Apply the rule for division by $10$, which involves moving the decimal point one place to the left.
• Step 3: Confirm the resulting value after the decimal shift.

Now, let's proceed with addressing each step:

Step 1: The number $12.2$ has its decimal point positioned after the digit $2$.

Step 2: Dividing by $10$ means moving this decimal point one place to the left, resulting in the decimal point being placed after the number $1$, turning $12.2$ into $1.22$.

Step 3: Thus, the value obtained is $1.22$.

Therefore, the solution to the problem is $1.22$.

To solve the problem of multiplying 1.52 by 10, we follow these simple steps:

• Step 1: Understand that multiplying a decimal number by 10 involves shifting the decimal point one place to the right.
• Step 2: Start with the number 1.52.
• Step 3: Shift the decimal point one place to the right to get 15.2.

Let's perform these steps:
Starting with 1.52, when we shift the decimal point one place to the right, we move from 1.52 to 15.2. This is because multiplying by 10 increases the value by one order of magnitude.

Thus, the product of $1.52 \times 10$ is $15.2$. Therefore, the correct answer choice is $15.2$.

To solve this problem, here's a step-by-step approach:

• First, identify the decimal number: $3.41$.
• Understand that multiplying by $10$ involves moving the decimal point one place to the right.
• Shift the decimal point in $3.41$ from between $3$ and $4$ to between $4$ and $1$, resulting in the number $34.1$.

Thus, the solution to the problem is $34.1$.
