Express the following answers with the correct number of significant figures.
3.582 ÷ 0.0131

Answer is 273

explanation:

The rule of division for significant figures is to put the answer to the least amount of significant figures presented in the problem.
0.0131 only has 3 sig figs which is 131
3.582 has 4 sig figs
The least amount is 3 in the problem
When you originally divide 3.582 and 0.0131 you get 273.4531 in your calculator

Now put it to 3 sig figs
4 is not greater than 5 so you don't need to round
273 is 3 sig figs.
So answer is 273

While unproven, it uses facts to support part of a conclusion. it is still factual and has predictive power, however.
