Question

An electrician requires 12 m 65 cm of wire to install a ceiling fan. He has a wire of length 18 m. After installing the fan, how much wire will be left? *

Answer 1

Wire left = 18m - 12m 65cm

Wire left = 5m 35cm

Answer 2

Given,

Total length of the wire = 18 m

Required length of the wire = 12 m 65 cm

To find,

The remaining length of wire.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now, we have to convert the given lengths into centimetre unit for the sake of easier calculations.

Total length = 18m = 1800 cm

Required length = 12 m 65 cm = 1265 cm

Remaining length = 1800-1265 = 535 cm = 5 m 35 cm

Hence,the remaining length of the wire is 5m 35cm.
