Answer: 20 times
Step-by-step explanation:
Given: The length of piece of wire = 10 millimeters
The length of screwdriver = 20 centimeters
We know that 1 cm = 10 mm
Therefore, the length of screwdriver = \(20\times10=200\) millimeters
The ratio of the length of screwdriver and length of wire is given by :-
\(\frac{\text{length of screwdriver}}{\text{length of piece of wire}}=\frac{200}{10}=20\)
The screwdriver is 20 times as long as the wire.
