Find the value of 2.2 + 4.08 + 3.125 + 6.3755.

Text Solution

Verified by Experts

Out of all the four numbers 2.2 has got the least number of decimal places - one.
Hence we should retain only two decimal places in the remaining numbers. Hence 4.08 remains as it is 3.125 is to be rounded off as `3.12` (as 7 before 5 is odd). Now adding `2.2 + 4.08 + 3.12 + 6.38 = 15.78`.
Finally we should have only one decimal place and hence 15.78 is to be rounded off as 15.8.
