Question

Calculate the value of 0.1394 + 0.004 correct to 2 decimal places

Answer 1

0.14

Step-by-step explanation:

First, we add the numbers to get the exact result of the sum

Therefore,

`0.1394+0.004=0.1434`

Note that the value of the 4th decimal place is not exact since we are given only 3 decimal places in 0.004; therefore, we can only say with reasonable confidence that

`0.1396+0.004=0.143`

Hence, the correct value to 2 decimal places is

`0.14`
