Answer: 200
Explanation:
To round 216x876 to 1 significant figure, we need to look at the first non-zero digit. In this case, the first non-zero digit is 2.
To determine the rounded value, we need to consider the digit to the right of the first non-zero digit, which is 1. Since it is less than 5, we round down the first non-zero digit to 2.
Therefore, 216x876 rounded to 1 significant figure is 200.
Hope this helps.
