How can you measure a 650 mm ribbon with a 30 cm ruler?
1 cm = 10 mm. Start with ruler at 0 and mark ribbon at 30 cm. Then place ruler at the mark and measure 30 cm more and make another mark- you are up to 60 cm or 600 mm. Then place ruler at this mark and measure 5 cm, or 50 mm. Now you have a 650 mm ribbon.
Where is the one and five eights mark on ruler?
All you have to do is find the eighth marks, start at one inch, and find 5/8ths after the one.
How do measure the length of an object with a ruler?
A ruler (some say it should be called a rule!) is marked along an edge with (nowadays) centimetres and millimetres. Place the zero mark on the ruler at the start of the object to be measured, and read off the measurement at the other end of the object.
Where is 80 centimeters on a ruler?
Between the 70 centimetre mark and the 90 centimetre mark.
Where on a ruler is 1.125 inches?
To find 1.125 inches on a ruler, first locate the 1-inch mark. From there, move an additional 0.125 inches, which is equivalent to 1/8 of an inch. This will place you at the first small mark after the 1-inch mark, which is typically the third mark on the ruler after the 1-inch line. Therefore, 1.125 inches is just past the 1-inch mark, at the first eighth mark.
