Determine the percentage of electricity generated in nuclear power stations that day.
Use data from Figure 6.
Determine the percentage of electricity generated in nuclear power stations that day.
Use data from Figure 6.
How to approach this question
1. A pie chart represents a total of 100%.
2. Read the percentages for all the given sectors from the chart: Solar, Coal, Gas, and Other.
3. Add these percentages together.
4. Subtract the total from 100% to find the missing percentage for Nuclear.
Full Answer
A pie chart shows parts of a whole, and the total must add up to 100%.
The percentages given are:
- Solar: 24%
- Coal: 23%
- Gas: 28%
- Other: 3%
First, sum these percentages:
Total known = 24 + 23 + 28 + 3 = 78%
The remaining part of the pie chart must be Nuclear. To find its value, subtract the known total from 100%:
Nuclear % = 100% - 78% = 22%
Common mistakes
✗ Simple addition or subtraction errors.
✗ Misreading the percentages from the chart.
✗ Forgetting to subtract from 100 and giving 78% as the answer.
