It depends on the accuracy of the ruler. If the smallest unit is 1/16 in, then you can read 2.2 in as 2 in + 0.2 in(16 units/1 in) = 2 in and 3.2 units

**Answer 2**

How to read a ruler

Rulers come in different measurements 1/4 , 1/8, 1/16, 1/32, 1/64

I will give you the 1/8 measurement

there are lines that represent the length of mesurement

1/8 first line.means one space from zero

2/8 or 1/4 second line. means two spaces from zero

3/8 third line. means three spaces from zero

4/8 or 1/2 forth line means four spaces from zero

5/8 fifth line. means five spaces from zero

6/8 or 3/4 sixth line. means six spaces from zero

7/8 seventh line. means seven spaces from zero

8/8 eight line. Mens eight spaces from zero

8/8 = one inch. The longest line

I am not sure of the measurement on you ruler. One way to find out is , count the lines to one inch and this will determine the type of ruler you have. The .2 on you ruler is the second line.
