Question

5.5 - 8.1

`5.5 - 8.1`
​

Answer 1

-2.6

Explanation:

The given expression is 5.5 - 8.1

Here, we need to subtract 8.1 from 5.5. 8.1 is a bigger number than 5.5.

So, we need to subtract a bigger number from a smaller number.

Therefore, we first subtract 5.5 from 8.1 and then mention the answer as negative.

First, we need to subtract the last digit of each. So, 1 -5. As 1 < 5, we borrow 1 from the neighboring digit and hence 1 becomes 11. The neighboring digit was 8 which will become 7.

Now, 11 - 5 = 6

Now, next, we subtract 7 and 5.

So, 7 - 5 = 2

Therefore, 8.1 - 5.5 = 2.6

Hence, 5.5 - 8.1 = -2.6
