Question

An electrician has 4.1 meters of wire how many strips 7/10 meter can he cut

Answer 1

Turn 7/10 into decimal. (0.7)

Keep adding by 0.7 until you get the number closest to 4.1

3.5 is the closest, if we add another 0.7, we get 4.2.

So, he can get 5 sections of 0.7m

Answer 2

The number of strips of 7/10 meters he can cut is:

5 strips

Explanation:

Total length of the wire that an electrician has is: 4.1 meters

Also, the length of each strips into which the wire is to be cut into pieces is: 7/10 meters= 0.7 meters

Hence, the number of wire of length 0.7 meters that could be made are:

Total length of wire/Length of one strip

= 4.1/0.7

= 5.8571

Now we know that the wire will exist as a whole.

This means that the number of strips of 0.7 meters will be: 5

whereas some extra wire will be leftover.
