all full centimeter values from 1 to 36 cm directly from the ruler. how do you find 5cm?Originally posted by cytokinesis
First at 18 in the middle
Then at 9
Divide that space in 3 so you have 1.5 and 3.0
And divide the 3.0 marking into 3 as well.
Nah, thats cheating, you must be able to read all full centimeter values from 1 to 36 cm directly from the ruler. no copying or using the ruler twice.after you have the first centimetre then you can copy the 1 cm length over the ruler to measure everything
