Question

estimate the sum of the following by rounding off to the nearest hundred and also found the actual sum 1.4567 + 2643 estimate sum actual sum​

Answer 1

I think you made a mistake in the value, but I tried to solve it..

Solution :

Actual Sum -

1.4567 +2643 = 2644.4567

So, actual sum is 2644.4567

Estimated Sum -

We have to round off both the numbers to nearest hundred.

1.4567 → 1.5

2643 → 2700

Now we will add both the estimated numbers.

1.5 + 2700

So, estimated sum is 2701.5
