Question 1. Three divers are below the surface of the sea. Anna is at -24 m, Ben is at -9 m and Cleo is at -17 m. Which diver is closest to the surface? Give a reason for your answer.
Ordering Negatives▶ Show worked answerHide worked answer
- M1: The surface is 0 and the diver with the greatest number is closest to it; compare -24, -9 and -17
- A1: Ben with a reason
Answer: Ben; -9 is greater than -17 and -24, so it is the closest to 0.[2 marks] - 2
