800
Explanation
## Step 1:Identify the first significant figure of the number 827. The first significant figure is the first non-zero digit from the left. In this case, it is 8.## Step 2:Determine the digit immediately after the first significant figure to decide whether to round up or down. Here, the second digit is 2.## Step 3:Since the second digit (2) is less than 5, we do not round up the first significant figure (8). Instead, we replace all subsequent digits with zeros.## Step 4:Thus, rounding 827 to 1 significant figure results in 800.
