A supermarket sells five types of milk made from plants. The pie chart shows the proportion of different plant milks the supermarket sold in one day. Altogether, the supermarket sold 180 litres on this day. How many litres of soya milk was sold on this day?

Rice = 50 ° Oat = 90 ° Coconut = 40 ° Almond = 120 ° Soya = 360 ° - 50 ° + 90 ° + 40 ° + 120 ° = 360 ° - 300 ° = 60 ° Total amount of the milks sold = 180 litres Amount of soya milk sold on that day = Measure of the degree which represents soya 360 ° × Total amount of milk sold on that day = 60 ° 360 ° × 180 litres = 30 litres Therefore, 30 litres of milk was sold on that day.

The waffle diagram shows the colours of the cars in a school's staff car park. Use the waffle diagram to complete the following table. Colour of car Number of cars Red 3 Blue Green Yellow White

Given: Number blue coloured cars = 5 Number green coloured cars = 8 Number yellow coloured cars = 1 Number blue coloured cars = 7 Therefore, the complete table is shown below: Colour of car Number of cars Red 3 Blue 5 Green 8 Yellow 1 White 7

The waffle diagram shows the colours of the cars in a school's staff car park. Draw a pie chart to show the information given in the waffle diagram.

Given: Number red coloured cars = 3 Number blue coloured cars = 5 Number green coloured cars = 8 Number yellow coloured cars = 1 Number white coloured cars = 7 Total number of cars = 3 + 5 + 8 + 1 + 7 = 24 Number of degrees per car = 360 ° Total number of coloured cars = 360 ° 24 = 15 ° Number of degrees of each sector = Number of cars of that particular colour × Number of degrees per car Red = 3 × 15 ° = 45 ° Blue = 5 × 15 ° = 75 ° Green = 8 × 15 ° = 120 ° Yellow = 1 × 15 ° = 15 ° White = 7 × 15 ° = 105 ° Therefore, the required pie chart is shown below: Enable Ginger Cannot connect to Ginger Check your internet connection or reload the browser Disable in this text field Rephrase Rephrase current sentence Edit in Ginger ×

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 °

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 ° Sofia says instead of working out the percentages and then the degrees, I think it is easier to work out the degree straight away like this, tea = 45 150 × 360 ° = 108 ° . Do you agree with Sofia or would work the percentages and then the degrees? Explain why.

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 ° Sofia says instead of working out the percentages and then the degrees, I think it is easier to work out the degree straight away like this, tea = 45 100 × 360 ° = 108 ° . 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:
