9. Solve Exercise 9 Page 11 Grade 7 Mathematics Workbook
Question: Figure 4 describes a weighing scale, where the marks read 46 and 48 respectively corresponding to the measurements of 46 kg and 48 kg. When looking at the position where the needle points, Minh reads the measurement as 47.15 kg, Dương reads the measurement as 47.3 kg, and Quân reads the measurement as 47.65 kg. Who read the measurement correctly? Why?
Guidelines for solving: Observe the smallest division of the scale and observe which number the needle points to.
Answer:
We observe each mark corresponds to 200g, the needle is just past the mark for 47 and a half, so it reads 47.3 kg.
So Dương read correctly, Minh and Quân read incorrectly.
