Answer 1

For addition and subtraction the answer should have the same number of decimal places as the least number of decimal places involved in the operation. For multiplication and division the number of significant value of the answer should be the same as the least number of significant values of the involved numbers.

a. 26 x 0.02584 = 0.67
b. 15.3: 1.1 = 14
c. 782.45 - 3.5328 = 778.92
