The waffle diagram shows the number of hot drinks sold in a cafe on a day. Use the diagram to complete the table. Hot drink Number of drinks Percentage of total Number of degree Tea 45 45 150 × 100 = 30 % 30 % of 360 ° = 108 ° Coffee Hot Chocolate Total 150 100 % 360 °

Number of coffee sold = 90 Percentage of the total = 90 150 × 100 = 60 % Number of degrees = 60 % of 360 ° = 60 100 × 360 ° = 216 ° Number of hot chocolate sold = 15 Percentage of the total = 15 150 × 10 = 10 % Number of degrees = 10 % of 360 ° = 10 100 × 360 ° = 36 ° Therefore, the complete table is shown below: Hot drink Number of drinks Percentage of total Number of degree Tea 45 45 150 × 100 = 30 % 30 % of 360 ° = 108 ° Coffee 90 90 150 × 100 = 60 % 90 % of 360 ° = 216 ° Hot Chocolate 15 15 150 × 100 = 10 % 10 % of 360 ° = 36 ° Total 150 100 % 360 °

I agree with Sofia because it will save a lot of time and, it will help us to make a pie chart more quickly.

The waffle diagram shows the number of hot drinks sold in a cafe on a day. Draw a pie chart to show the information given in the waffle diagram.

Total number of drinks sold = 150 Number of coffee sold = 90 Percentage of the total = 90 150 × 100 = 60 % Number of degrees = 60 % of 360 ° = 60 100 × 360 ° = 216 ° Number of hot chocolate sold = 15 Percentage of the total = 15 150 × 100 = 10 % Number of degrees = 10 % of 360 ° = 10 100 × 360 ° = 36 ° Number of tea sold = 45 Percentage of the total = 45 150 × 100 = 30 % Number of degrees = 30 100 × 360 ° = 108 ° Therefore, the complete table is shown below: Hot drink Number of drinks Percentage of total Number of degree Tea 45 45 150 × 100 = 30 % 30 % of 360 ° = 108 ° Coffee 90 90 150 × 100 = 60 % 90 % of 360 ° = 216 ° Hot Chocolate 15 15 150 × 100 = 10 % 10 % of 360 ° = 36 ° Total 150 100 % 360 ° Therefore, the pie chart is drawn below:

The infographic shows the mass of bananas produced by different countries. Which country produces the most bananas?

Quantity of bananas produced in India = 11 million tonnes Quantity of bananas produced in Brazil = 6 . 3 million tonnes Quantity of bananas produced in China = 4 . 8 million tonnes Quantity of bananas produced in Ecuador = 6 million tonnes Therefore, the country which produces the most bananas is India producing 11 million tonnes.
