Estimate the following difference using front-end estimation.

788.44 - 225.6

500
600
700
400

The answer is 600

Step-by-step explanation:

Front end estimation is a method of rounding use to make operations more easily and obtain approximate answers. Is called front end because we take the first digit of the number or the "front digit" and round our number to the nearest value detemined by our front end digit, making zeros the other numbers until the end.

In your case we have:

788.44 - 7 is the front number - in hundreds place -  we round to nearest hundred 788.44 and this is 800.

225.6  - 1 is the front number - in hundreds place - we round to nearest hundred 225.6  and this is 200.

We perform the operation and obtain : 800-200 = 600.

Answer Is 500. If it's wrong that's not me. I know, bc I did it.

Step-by-step explanation:

if x = 1, then the answer is 3.5

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
