Question

Write down the answer. Make sure to use the correct number of sig figs or

spots after the decimal. 987.22 - 377.1*

Answer 1

610.1

Step-by-step explanation:

When we add or subtract the values, the number of significant figures after decimal in result must be equal to the given measurement having less number of decimal places.

In given values 377.1 has only decimal place thus in result after decimal there should be one digit only.

987.22 - 377.1 = 610.1

When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.

Now we will calculate the difference between 7.69 and 4.0.

7.69 - 4.0 = 3.69

In given values 4.0 have less number of significant figures thus result must have only two significant figures . So we would round the result.

3.7
