What is the product of 1.75 and 2.4?

Explanation:
When you multiply decimals, multiply as if they’re whole numbers and then place the decimal point based on the total number of digits to the right of the decimal in both factors. For 1.75 and 2.4, treat them as 175 and 24. Multiply: 175 × 24 = 4200. The first number has 2 decimal places and the second has 1, for a total of 3 decimal places. Put the decimal point 3 places from the right in 4200, giving 4.200, which simplifies to 4.2. So the product is 4.2. The other options don’t match this decimal placement result.
