\( 2.31\times10= \)
We will solve the problem by multiplying by . When multiplying a decimal by , the decimal point moves one place to the right.
Let's follow the steps:
Therefore, multiplying by gives us the result .
The solution to the problem is .
Answer:
To solve this problem, we'll follow these steps:
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 .
Therefore, the solution to the problem is .
Answer:
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: We are given the number to multiply by .
Step 2: Multiplying by moves the decimal point one position to the right.
Step 3: Performing this shift, becomes , which simplifies to .
Therefore, the solution to the problem is .
Answer:
To solve this problem, we'll follow this straightforward approach:
Now, let's perform the calculation:
The number has a decimal point after the first digit, and when we shift the decimal one place to the right, it moves between and , resulting in .
Therefore, the product of multiplied by is .
Thus, the solution to the problem is .
Answer:
To solve this problem, we'll follow these steps:
Now, let's work through these steps in detail:
In Step 1, we confirm that the problem provides the number to be divided by .
In Step 2, we apply the rule of decimal division by shifting the decimal point in one place to the left. This means the decimal moves from between the "111" and the "1" to between the "11" and "11". Thus, the number becomes .
Therefore, the solution to the problem is .
