Question

An electrician has a wire 6 meters long. She needs to cut it into 12 equal pieces. How many centimeters long will each piece be?

Answer 1

For this case, we must say how much each piece of cable measures, by dividing the original cable into 12 equal pieces.

So:

$\frac {6} {12} = \frac {1} {2} = 0.5\ meters$

Thus, each piece will be 0.5 meters long, after having been cut.

Knowing that:

1 meter equals 100 centimeters, we make the following rule of three:

1 m --------------> 100 cm

0.5 m ------------> x

$x = \frac {0.5 * 100} {1}\\x = 50\ cm$

Thus, each piece will have 50 centimeters.

Answer:

Option B

Answer 2

The answer would be A because you just divide 12/6
