Question

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 nearest 10cm. What is the largest number of fence posts that can possibly be cut from the log?

Answer 1

Answer:

25 posts

Step-by-step explanation:

So the number of fence post would be the total length of the log divided by the length of each post. As the log is 16m and is corrected to the nearest metre, it could possibly be 16.499m. As for the post that is 70 cm long and corrected to the nearest 10cm, it may as well be 65 cm (or 0.65m) each post

So the max number of fence point once can possibly cut from the log would be

16.499 / 0.65 = 25 posts
