Answer:
22 fence posts.
Explanation:
To find the largest number of fence posts that can be cut from the log, we need to first convert the length of the log and the length of each fence post to the same unit of measurement. Let's convert everything to centimeters (cm).
The length of the log is 16 m = 1600 cm (since 1 m = 100 cm).
The length of each fence post is 70 cm.
To find the number of fence posts that can be cut, we divide the length of the log by the length of each fence post and round down to the nearest whole number (since we are told to round to the nearest 10).
So, the number of fence posts that can be cut is:
1600 cm ÷ 70 cm = 22.857...
Rounding down to the nearest whole number, we get:
22 fence posts.
Therefore, the largest number of fence posts that can be cut from the log is 22.
