Question

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

Answer 1

Answer:

0.14

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

$0.14$
