How do you use a centimeter ruler?
In the same way that you would use any other ruler except that you use the centimetre scale.
What does 0.8 look like on a ruler?
On a standard ruler, 0.8 would be located 8/10 of the way between the 0 and 1 marks. This would be 8 millimeters or centimeters, depending on the scale of the ruler. Visually, it would be closer to the 1 mark than the 0 mark, but not all the way there.
How can you measure length without a ruler?
You can guess, that's the only way.
How do you draw a circle with a pencil and ruler?
Use the ruler to measure the size of the circle you want - this will be a line all the way across the whole circle. Then, measure a piece of string with the ruler -- make this half the size of the original line. Use a thumbtack to tack the string in the spot you want the middle of your circle. Use a bit of tape to tape the other end onto your pencil (don't wrap it around or you will end up with a smaller circle!) Gently move the pencil around the thumbtack to make your circle.
How will you measure length using a broken ruler?
A broken ruler still has lines of measurement on it - it's just not as convenient as it was when it was whole. You measure the same way, by holding the ruler next to the item you're measuring and deciding which line it reaches to. With a broken ruler, you will probably have to measure one part at a time and add the measurements together.
