Find the value of 2.2+4.08+3.125+6.3755. |
|
Answer» Solution :Out of all the FOUR numbers `2.2`has got the LEAST number of DECIMAL PACES -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 2before 5 is even ) `6.3755` is to be rounded of as `6.38`(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.` |
