For addition and subtraction, first, we have to see the decimal portion of the question and count them (digits right to the decimal place). Then add or subtract in the normal fashion. Then round the answer to the least number of places in the decimal portion of any number in the problem.
The answer should contain 3 decimal points
b. 65.557 + 35.75 = 102.302
In the question, one part has 3 digits and other has 2 digits after decimal point. Thus while reporting answer it should contain 2 digits after addition. (if the next digit is above 5, u can round off)
Thus our answer is 102.30
It has 2 decimal points.
79.427 * 78.153 = 6207. 458331
In the question, it has only 3 decimal points thus it should be reported as 6207. 458 and it has 7 significant figures
d. 66.557 /35.75 = 1.86173426
