Answer: The largest number of fence posts that can possibly be cut from the steel bar is 28
Explanation:
To determine the largest number of fence posts that can possibly be cut from the steel bar, we first need to find the minimum and maximum lengths of the steel bar and fence posts based on their respective measurements.
Steel bar length: 15 m, correct to the nearest meter
Minimum length: 14.5 m (0.5 m less than 15 m)
Maximum length: 15.5 m (0.5 m more than 15 m)
Fence post length: 60 cm, correct to the nearest 10 centimeters
Minimum length: 55 cm (5 cm less than 60 cm)
Maximum length: 65 cm (5 cm more than 60 cm)
Now, we convert all measurements to the same unit (e.g., centimeters).
Minimum steel bar length: 14.5 m * 100 cm/m = 1450 cm
Maximum steel bar length: 15.5 m * 100 cm/m = 1550 cm
To maximize the number of fence posts that can be cut from the steel bar, we will use the maximum steel bar length and the minimum fence post length:
Number of fence posts = Maximum steel bar length / Minimum fence post length
Number of fence posts = 1550 cm / 55 cm ≈ 28.18
Since the number of fence posts must be a whole number, we round down to the nearest whole number: 28
