0.15×200=
\( 0.15\times200= \)
\( 1.23\times180= \)
\( 0.4\times115= \)
\( 1.23\times110=\text{ ?} \)
\( 14.6\times150= \)
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: We need to find the result of multiplying by .
Step 2: Multiply as if is , then apply appropriate scaling for the decimal places:
Step 3: Since has two decimal places, divide the result by :
Therefore, the solution to the problem is .
To solve this problem, we'll follow these steps:
Let's go through each step:
Step 1: We start by calculating the product of and . Multiplying the numbers without considering the decimal initially, we treat it as .
Step 2: Calculate . This can be split into simpler calculations, :
-
-
Adding these: .
Since has two decimal places, we place the decimal point back in the product, which gives us , or simplified, .
Therefore, the solution to the problem is .
To solve this problem, we need to calculate the product of and .
First, let's perform the multiplication:
Multiply by :
Here's how the calculation works step-by-step:
Thus, the solution to the problem is .
We will use the distributive property to split 110 into two numbers—100 and 10.
Now we will multiply the original number (1.23) by these two numbers:
1.23*100=123
1.23*10=12.3
All that is left to do is to add the two products together to get our answer:
123 + 12.3 = 135.3
To solve this problem, we'll proceed with these steps:
Step 1: Consider 14.6 as 146, so multiply 146 by 150:
Step 2: Since we treated 14.6 as 146 (multiplied by 10 initially), divide the result by 10:
Therefore, the product of is .
\( 0.113\times170= \)
\( 5.11\times110= \)
\( 3.12\times109= \)
\( 11.2\times101= \)
To solve this problem, we'll use straightforward multiplication while carefully considering the decimal place. Here are the steps we'll follow:
Step 1: Treat as by ignoring the decimal point temporarily.
Step 2: Multiply .
Step 3: Reintroduce the decimal point in the product by placing it three decimal places from the right, as in .
Let's work through each step:
Step 1: We rewrite as .
Step 2: Multiplying by yields:
Step 3: Now place the decimal point. Since the original number had three decimal places, the product must be adjusted to three decimal places from the right, yielding:
Thus, the final answer is:
To solve this problem, we'll multiply the decimal number 5.11 by the integer 110. To do this, we'll follow these main steps:
Therefore, the solution to the problem is .
To solve , we proceed as follows:
Therefore, the solution to the multiplication is .
To solve this problem, we'll use the distributive property of multiplication:
Now, let's execute each step:
Step 1: Write as .
Step 2: Use the distributive property:
