Answer
\( 2.4 \times 3.7 = 8.88 \)
Solution
To multiply 2.4 by 3.7, you can follow these steps:
1. Ignore the decimal points and multiply the numbers as if they were whole numbers: multiply 24 and 37.
• 24 × 37 = 888
2. Count the total number of decimal places in the original numbers. In 2.4 there is 1 decimal place, and in 3.7 there is also 1 decimal place, adding up to 2 decimal places.
3. Place the decimal point in the product so that it has 2 decimal places. Thus, 888 becomes 8.88.
So, 2.4 × 3.7 = 8.88.

To multiply 2.4 by 3.7, you can first ignore the decimals and multiply as if they were whole numbers: \( 24 \times 37 = 888 \). Next, you add the total number of decimal places from both numbers (2 from 2.4 and 1 from 3.7, making it 3). Thus, you move the decimal point 3 places to the left in 888, resulting in \( 8.88 \). So, \( 2.4 \times 3.7 = 8.88 \). A handy tip to avoid common mistakes is to neatly line up the numbers for clarity if you're doing the multiplication by hand. You can also finish by double-checking that you haven't missed any decimal moves—the safety net for avoiding decimal disasters!
