1.69

Step-by-step explanation:

This is correct :)

Answer 2

1.69.

Step-by-step explanation:

• The solution = 12.0 / 7.11 = 1.687 = 1.69.

• The rule of significant figures for division states that: the results are reported to the fewest significant figures.

• 12.0 contains 3 significant figures.

• 7.11 contains 3 significant figures.

So, the solution should contain 3 significant figures.

• Now, the issue id of rounding; In a series of calculations, carry the extra digits through to the final result, then round.

• If the digit to be removed is equal to or greater than 5, the preceding digit is increased by 1.

• The digit that should be removed is 7 that is larger than 5 so increase the preceding digit by 1.
