(give solution step by step)
; )​

Answer 1

Answer:

5 wires are of 250 mg

now 1 kg = 1000000 mg

Number of wires whose weight 1 kg are = (1000000×5)/250 = 20000

Answer 2

Given:

Mass of 5 thin gold wires is 250mg

To find:

How many wires will weigh 1 kg

Solution:

5 wires are of 250mg

Now, we need to find how many 'mg' makes 1kg

So, 1kg= 1000000mg

Number of wires weighing 1kg are= dividing 1000000mg by250mg

                                                         = 1000000/250

                                                         = 4000

Therefore, 4000 thin gold wires would weigh 1kg.
