    Hi

    I don’t understand pie charts that have numbers over 100.

    example :the table gives information about the lunch arrangements of 900 students.

    choice freqency

    full meal 200
    Hot snack 290
    cold snack 260
    Packed lunch 150

    Hi Anujaa,

    you need to see how those 900 students will fit into 360 degrees.

    if you divide both numbers by 90 you get 10 students is 4 degrees

    so 5 students is 2 degrees

    Use these to work out your angles.
