2.8 In On A Ruler

Hither we will explain and show yous where 2.8 inches is on a ruler. More specifically, we will give you step-by-step instructions on how to find, and then illustrate, where 2.viii is located on a ruler.

The ruler is divided up into whole inches: 1 inch, ii inches, 3 inches, and so on. Outset, we will decide between which two whole inches 2.8 fits. ii.8 is greater than 2 and less than 3. Therefore, two.8 is located between 2 inches and iii inches on the ruler.

If you look closely at a ruler, y'all will see that there are 15 marks between each inch, dividing each inch into 16 equal parts. Below are the lengths to each marking from any whole inch:

Mark 1: 0.0625
Mark 2: 0.125
Mark 3: 0.1875
Mark iv: 0.25
Mark v: 0.3125
Marker 6: 0.375
Mark 7: 0.4375
Marking 8: 0.5

Mark nine: 0.5625
Marker 10: 0.625
Mark 11: 0.6875
Mark 12: 0.75
Mark 13: 0.8125
Mark 14: 0.875
Mark 15: 0.9375

Looking at the table above, we tin can locate where the decimal part of 2.viii fits. The decimal part of 2.8 is more than than 0.75 and less than 0.8125. Therefore, 2.8 fits between Marker 12 and Mark thirteen.

Now the hardest part, which is to observe where between Marker 12 and Mark 13 that two.viii is located. We showtime by computing the distance between 0.75 and 0.viii like this: 0.eight - 0.75 = 0.05.

In that location are 0.0625 inches betwixt each mark, and we can summate what percent 0.05 is of 0.0625 like this: (0.05 × 100) ÷ 0.0625 = lxxx%

This means that 2.eight is 80% of the altitude between Mark 12 and Mark xiii.

Now we have all the information we need to testify you where on our ruler 2.8 is located. two.8 is located betwixt 2 inches and 3 inches, and 80% of the distance betwixt Mark 12 and Mark xiii. Our analogy below shows two.8 inches marked with a red pivot.
