The final answer is 13.345.
B) 13.35
Step-by-step explanation:
To calculate the result of 3.14 * 4.25, follow these steps:
Step 1: Write down the numbers you want to multiply.
Step 2: Multiply the numbers as you would with whole numbers, ignoring the decimal points for now.
Step 3: Count the total number of decimal places in both numbers. In this case, 3.14 has two decimal places and 4.25 also has two decimal places. Thus, together there are 2 + 2 = 4 decimal places.
Step 4: Multiply the numbers without considering the decimal point. That would be the same as multiplying 314 by 425.
Step 5: 314 x 425 = 133450 (you can perform this multiplication on paper or using a calculator).
Step 6: Since there are 4 decimal places in the original numbers, we need to place the decimal point in the product accordingly. So we count four digits from right to left in our product 133450, placing the decimal point to give us 13.3450, which can be simplified to 13.345 by removing the trailing zero.
Therefore, the final result is 13.345, which is closest to option B) 13.35.
