Walk is a 90 degree angle because of the angle marker
Bus is given
360-90 gives the total for bike,bus,car
=270-120= 150 (120 is from the given)
150 is what is left for bike and car
I say your best is to divide that by 2 but you don’t know the exact degree but those two seem pretty well even so 150/2= 75 aka 75 for both bike and car
Now that you know the degrees you have to find the percents. 360=1 circle
Walk=90/360=.25•100=25%
Bus=120/360=.33•100=33%
Bike=75/360=.208•100=21% (rounded)
Car is the same as bike=21%
Add up percents and it should add up to 100 to check.
Now back to the decimals. Sorry for the inconvenience.
Use .25•(total number of pupils)=9 pupils that walked.
Do that for each one and at the end all your answers for the boxes should add up to 36
