A log is 16m long, correct to the nearest metre. It has to be cut into fence posts which must be 70cm long, correct to the neare

Answer:

25 posts

Step-by-step explanation:

To find the number of fence posts, you divide the log's total length by the length of each post. Given the log is 16m, corrected to the nearest meter, it could be as long as 16.499m. Each post should ideally be 70 cm long but, adjusted to the nearest 10cm, could be considered 65 cm (or 0.65m) each.

Thus, the maximum number of fence posts that could be cut from the log would be

16.499 / 0.65 = 25 posts
