Question

An electrician bought 500 metres of wire. He sold 43 m 75 cm of the wire to one customer and 158 m 50 cm of it to another customer. What length of wire is now left with him?​

Answer 1

Answer:

297 m 75 cm

Step-by-step explanation:

Firstly convert all the values given in metres to centimetres so the calculation would be easy.

1 m = 100 cm

thus,

500 m = 500 x 100 -> 50,000 cm

43 m = 43 x 100 -> 4300 cm

        43 m 75 cm = 4300 + 75 -> 4,375 cm

158 m = 158 x 100 = 15,800 cm

        158 m 50 cm = 15800 + 50 -> 15,850

Now do the calculations,

First,

50,000 - 4375 = 45,625

Next,

45,625 - 15850 = 29,775

Therefore,

The length of wire left with him = 29,775 cm

If the required answer is in metres simply divide the ans by 100

$\frac{29775}{100}$

= 297.75

thus, answer is 297 m 75 cm.
