Explanation:
To multiply decimals, we can simply multiply the numbers as if they were whole numbers and then count the total number of decimal places in the factors. In this case, we have:
25.5 x 10 x 10 = 255 x 10
Now, we multiply 255 by 10 as if they were whole numbers:
255 x 10 = 2550
Finally, we count the total number of decimal places in the factors, which is two (one in 25.5 and one in 10). Therefore, the answer should have two decimal places, so we can add a decimal point to the result and place two zeros after it:
25.5 x 10 x 10 = 2550.00
Therefore, 25.5 x 10 x 10 = 2550.00.
