Reading Scales - Tutorial 3
This tutorial looks at reading a weighing machine scale, like those used in a kitchen.
| Weighing Machine |
The picture shows a Weighing Machine scale. As you can see, the large markers measure every 100, the medium markers measure every 50 and the small markers measure 10s.
The table below shows the results for the settings. Study this table and make sure that you understand how the readings are done.
| Setting | To Nearest 10 | To Nearest 50 | To Nearest 100 |
| A | 50 | 50 | 100 (remember to round up if half way) |
| B | 70 | 50 | 100 |
| C | 210 | 200 | 200 |
| D | 290 (this one is not quite half way between 290 and 300, so round down) |
300 | 300 |
| E | 350 | 350 | 350 |
Remember if the marker is exactly half way, then you round up.
To practise reading a Freezer Thermostat try this assessment. Remember to check what the questions want you to round to. (Either units, 5s or 10s)
