Question

An equipment shipment arrives. The shipping slipstates that the total weight is 140 kg, but the actualweight is 132 kg and 9 hectograms. What's the weightof the missing equipment?

Answer 1

To find out what's the weight missing we must subtract the expected weight from the actual weight.

The expected weight is 140kg, the actual weight is 132kg and 9 hectograms, remember that 1 hectogram 0.1kg, then 9 hectogram is 0.9. Then the actual weight is 132.9kg.

The weight of the missing equipment will be

$140-132.9=7.1\text{ kg}$

The weight of the missing equipment is 7.1 kg
