For addition and subtraction, round the result to match the measurement with the fewest decimal places. For example,

3.4 cm + 4.75 cm = 8.2 cm

because 3.4 cm is only measured to the nearest 0.1 centimeter.

Choose the answer with the correct number of significant digits.

Answer:

7 cm

Explanation:

If the following digit is greater than or equal to 5, the decimal place is rounded up (moved up to the next number); if the following digit is less than 5, the decimal place stays the same.

4.6 + 2.35 = 6.95 cm

However, as stated in your question, cm is only being measured to the nearest 0.1 centimeters in your question.

So, you would round the digit 9 up by 1, meaning you would round it to 10. However, there are only nine digits available in our base-10 counting system, so you carry the value over,

6.95 cm could be rounded to '6. 100 cm', which is 7 cm.
