Question

If a box of quartz weighs 10 kg (precise to ones place), how much does the same volume of corundum weigh?

Answer 1

Answer:

1 kg

Explanation:

Because if it's precise to the ones place, then it would be 1.0 kg. So the corundum would weigh 1 kg. and your just moving the 10 over one to the right  so the dot is now between 1 and 0 making it 1.0.
