Perform each calculation to the correct number of significant figures.

(a) 1459.3 + 9.77 + 4.32

(b) 0.004 + 0.09879

(c) 432 + 7.3 - 28.523

(d) 2.4 + 1.777

Step 1 of 4

Here we have to calculate the correct number of significant figures.

There are certain rules to track the significant figures from the calculated values. These are:

(a) For addition and subtraction, the result should contain same number of decimal places, as the measurement is carried out with the fewest decimal places.

(b) For multiplication and division, the result should contain same number of decimal places, as the measurement is carried out with the fewest significant figures.

(a) 1459.3 + 9.77 + 4.32

= 1473.39

= 1473.4

The significant figures of (a) is 1437.4 (five). This is because 1459.3 has only one decimal places.

Therefore , 5 significant figures are there in (a)

Thus correct number of significant figures of (a) is 1473.4
