Answer:

13.6

Explanation:

  • The rules for counting significant figures in addition:

1- The result should contain the decimal points as the fewest one of the added numbers.

12.77 has two decimals and 0.8 has 1 decimal, so the result should contain 1 decimal.

The result of (12.77 + 0.8) is 13.57.

2- Now, we should minimize the result to contain 1 decimal, so we round the number beside the first decimal (7).

It is higher than 5, so increase the first decimal by 1.

So, the final result is 13.6.

The solution to the problem rounded to the correct number of significant figures is 13.6.

What is the solution to problem?

The solution to the given arithmetic problem is calculated as follows;

12.77 + 0.8 = 13.57

The above solution can be rounded up since 7, after 0.5 is more than 5.

Any number after the decimal point greater than 5 is rounded up by calling the number 1 and adding it to the preceding number.

13.57  = 13.6 (3 significant figures)

Thus, the solution to the problem rounded to the correct number of significant figures is 13.6.
