Draw a tape of 10 squares each square representing 10%
put 0 at the beginning and 180 at the end
Determine how much 10% of 180 (180/10 or 180*.1)
Indicate on tape diagram the increasing amounts at each 10% break
That will show 90% of 180 on a tape diagram
0 10 20 30 40 50 60 70 80 90 100 percent
|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|
0 18 36 54 72 90 108 126 144 162 180
Can you see?
you could use other intervals for your tape diagram, I just find 10%s the easiest for this problem
