Lets get an example, for this example lets use 24/30 x 30/60
Without dividing out GCFs you would get 24x12 over 30 x 60 which is 288/1800
With dividing out GCFs you get 2/1 x 5/1 Which is 7 :)
The mean= 5.5
The median= 6
The range= 10
The IQR= 5
I really hope this helps:)
Ok -13*-8 is 104.
-8*18q is 144q.
Combine an you get:
144q+104
