Final answer:
The expression equivalent to 5.4 times 0.18 is solved by multiplying the two numbers and placing the decimal point correctly in the answer, resulting in 0.972.
Step-by-step explanation:
The expression equivalent to 5.4 times 0.18 is a multiplication problem that can be solved directly. We multiply the two decimals just like whole numbers and then place the decimal point in the final answer. Starting with 5.4 (which has one decimal place) and 0.18 (which has two decimal places), we multiply them as whole numbers:
• 54 x 18 = 972
Since there are three decimal places in total (one from 5.4 and two from 0.18), we place the decimal point three places from the right in our answer:
• 5.4 x 0.18 = 0.972
Therefore, 5.4 times 0.18 is equivalent to 0.972.
