How to multiplying Decimals by multi digit Whole numbers
In this section Multiply decimals by whole numbers examples & worksheets PDF, we’ll solve the case through two different methods. Both of them are very easy to understand and will give you more math skills.
1st Method: Multiply 22.6 x 38
First multiply the two numbers without decimal part. That means instead to solve the multiplication expression 22.6 x 38, you solve 226 x 38.
The answer is 8588
Now, count the decimal place you have in all. Since you have only one decimal number, it is quite simple:
You get 22.6 which has 1 decimal place.
You got the result 8588 for your last multiplication expression and you need to add 1 decimal place on it:
You get 858.8
22.6 x 38 = 858.8
2nd Method: How to multiply 22.6 x 38
Here is another way to multiply decimals by whole numbers; let’s solve the same example with another method.
There is one decimal digit in the factor 22.6
Whole number is 38 and it is not a multiple of 10.
Now, estimate the product.
Estimation of 22.6 is 20 and that of 38 is 40 because the estimated number must be multiple of 10.
Now, multiply to find the product. 40 x 20 = 800
Now, multiply to find the product.
Compensate by placing the decimal point in the product.
