How to approach this question
1. From the bar chart, find the percentage of the UK population who report using YouTube.
2. The population is given as 68 million.
3. Calculate the number of people who use YouTube by finding the percentage (from step 1) of the total population (68 million).
4. Compare your calculated number to Simran's claim of "nearly 55 million".
5. Write a comment stating whether she is correct and justify it with your calculation.
Full Answer
The statement is correct. Calculation: 80% of 68 million is 0.80 * 68,000,000 = 54,400,000, which is "nearly 55 million".
First, we find the percentage of the population that used YouTube from the graph. The bar for YouTube goes up to 80%.
Next, we calculate 80% of the total population, which is 68 million.
Calculation: 0.80 × 68,000,000 = 54,400,000.
Simran's statement says "nearly 55 million people". Our calculated value of 54.4 million is very close to 55 million.
Therefore, this part of Simran's statement is correct.
Common mistakes
✗ Using the wrong percentage from the graph.\n✗ Making a calculation error when finding the percentage.\n✗ Failing to make a concluding comment about whether Simran is correct.
