Question

A trophy store wishes to make brass medallions, each of mass 17.5 g, from 140 kg of brass. How many medallions can be made?

hint Hint:

Make the necessary conversions and thus get the number of medallions that
can be made.

The correct answer is: 8000

Complete step by step solution:
Total brass available = 140 kg
We know that 1 kg = 1000 grams.
So here, 140 kg = 140 $cross times$ 1000 = 140000 grams
Mass of one medallion = 17.5 grams
∴ Total number of medallions that can be made from 140000 grams = $fraction numerator 140000 over denominator 17.5 end fraction$
$not stretchy rightwards double arrow fraction numerator 140000 over denominator 17.5 end fraction equals 8000$
Hence 8000 medallions can be made from 140 kg of brass.
