Question

A copper wire is 17 1upon2 metre long if 13 1 upon 4 metre is used in electric fitting how much why is left​

Answer 1

Step-by-step explanation:

okay !

we have

$17 \times \frac{1}{2} m \: long wire$

$13 \times \frac{1}{4} m \: is \: used \: in \: electric \: fitting \: .$

Now, we have to find the left part.

we will subtract it so it will come the answer

$= 17 \times \frac{1}{2} - 13 \times \frac{1}{4}$

$= \frac{35}{2} - \frac{53}{4}$

$= \frac{70 - 53}{4}$

$= hence \: \frac{17}{4} wire \: is \: left \: \: after \\ \: used \: in \: electric \: fitting \: .$
