Question

Which decimal number does arrow represent?

• A. $3.05$
• B. $3.025$
• C. $3.005$
• D. $3.004$

Answer 1

The correct option is C $3.005$

Let the marking $3.00$ is at $A$ and $3.01$ is at $B$

$AB=3.01-3.00=.01$

Number of units betwwen $A$ and $B$ $=10$

Length of each unit $=\frac{.01}{10}=.001$

Given point is $5$ units from $3.00$

So location of given point is $=3.00+.001\times 5=3.005$

Option $C$ is correct.
