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.

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 don’t! Turn the fraction you are dividing by upside down and multiply instead.

eg 5/8 divided by 3/4

becomes 5/8 x 4/3 = 20/24 = 5/6

Do both calculations on your calculator to convince yourself this works.
