What is the product of 1.5 and 7?
Correct Answer:
10.5
Explanation:
When multiplying a decimal by a whole number, multiply as if there were no decimal, then place the decimal point based on the total number of decimal places in the factors. Here, 1.5 has one decimal place and 7 has none, so the product carries one decimal place. Multiply 15 by 7 to get 105, then place the decimal one place from the right to get 10.5. You can also visualize it as 7 × 1.5 = 7 × (1 + 0.5) = 7 + 3.5 = 10.5. So the product is 10.5. The other options would come from different multipliers or decimal placements, not this case.
