Answer:
Explanation:
To write 236 correct to one significant figure, we follow these steps:
Step 1: Determine the first significant figure.
The first significant figure is the first non-zero digit in the number. In this case, the first non-zero digit is 2.
Step 2: Keep only the first significant figure.
Since we want to write the number to one significant figure, we keep only the first significant figure, which is 2.
Step 3: Round the number if necessary.
If the digit immediately following the first significant figure is 5 or greater, we round up. If it is less than 5, we round down. In this case, there is no digit following the first significant figure.
Therefore, the number 236 written to one significant figure is 200.
So, 236 correct to one significant figure is 200.
