If 81 ⋅ 432 = 34,992, what is 8.1 × 4.32? (1 point)
8.1 × 4.32 = 34.992
To find the product of 8.1 and 4.32, follow these steps:
1. Remove the decimal points: 81 becomes 810 and 4.32 becomes 432.
2. Multiply the two numbers without decimal points: 810 × 432 = 349,920.
3. Count the number of decimal places in the original numbers. In this case, 8.1 has one decimal place and 4.32 has two decimal places.
4. Place the decimal point in the answer by counting from the rightmost digit: 349,920 becomes 34,992.0 (the decimal point is placed three places from the right to account for one decimal place in 8.1 and two decimal places in 4.32).
Therefore, the product of 8.1 × 4.32 is 34,992.0.
