Problem Solving & Reasoning
Solve these multi-step problems and explain your reasoning.
1.
An engineer needs to cut steel beams that are approximately 1,245 meters long. To minimize waste, she rounds the length to the nearest 100 meters before cutting. What length will she use for each beam?
[3 marks]2.
A construction site measures 2,348 meters of fencing. The workers round this measurement to the nearest 100 meters to estimate the amount of fencing needed. How much fencing do they estimate they have?
[3 marks]C
Real-world Applications
Apply your rounding skills to these engineering scenarios.
1.
A bridge construction project requires steel cables approximately 2,876 meters long. The supplier reports lengths rounded to the nearest 100 meters. What is the possible range of actual cable lengths?
[3 marks]2.
A scaffolding section is measured at 1,234 meters. Round this measurement to the nearest 100 meters for inventory purposes.
[1 mark]D
Challenge & Extension
Tackle these more advanced problems involving rounding in engineering contexts.
1.
An engineer is reviewing measurements of 4,567 meters for a new project. She rounds each measurement to the nearest 100 meters for planning. What is the rounded measurement?
[2 marks]2.
A set of metal rods are approximately 9,432 meters long. The manufacturer reports lengths rounded to the nearest 100 meters. What is the maximum possible actual length of any rod?
[3 marks]E
Mixed Review
Answer these questions to review your understanding of rounding in engineering contexts.
1.
Round 3,987 meters to the nearest 100 meters.
[1 mark]2.
A bridge length measurement of 2,045 meters is reported. Round it to the nearest 100 meters for project documentation.
[1 mark]F
Error Analysis
Identify and correct the common mistake in the following rounding problem.
1.
Error: Rounding 1,253 meters to the nearest 100 meters results in 1300. Is this correct? If not, what is the correct rounded value?
