Question

A screwdriver is 20 centimeters long, and a piece of wire is 10 millimeters long. The screwdriver is how many times as long as the wire?

Answer 1

I believe it is 20 because if you times 10 2  times you will get your answers

Answer 2

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.
