To calculate the result of 1.388 times 3.26, we multiply these two numbers together.
Multiplication Process
The multiplication of 1.388 by 3.26 involves multiplying each digit of one number by each digit of the other and then summing the results, taking into account the decimal places. Given the numbers are decimals, we treat them as fractions of a whole for the purpose of this calculation.
Step-by-Step Calculation
First, we ignore the decimal points and multiply 1388 by 326.
| Multiplier | Multiplicand | Product |
|---|---|---|
| 1388 | 326 | 452488 |
Next, we determine the total number of decimal places in both numbers, which are 3 in total (3 from 1.388 and none additional from 3.26 since it has fewer decimal places but we consider its implicit decimal). We then place the decimal point in our product, 452488, to reflect this, resulting in 452.488.
Result
The result of multiplying 1.388 by 3.26 is 4.52488, which can be rounded to 4.52 for most practical purposes.
Verification
This calculation can be verified using a calculator or computer program designed for mathematical operations to ensure accuracy.
How do I ensure the decimal point is correctly placed in the product of a multiplication involving decimals?
+To ensure the decimal point is correctly placed, count the total number of decimal places in the factors. Then, place the decimal point in the product so that it has the same number of decimal places as the sum of the decimal places in the factors.
