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
