It doesn't matter HOW you do the division. You can use a calculator, long division, mental math, short division, a slide rule, a Curta, or an abacus. Every possible method must deliver the same answer. If it doesn't, then either you made a mistake using it, or else the method itself doesn't work.
So I'm not going to tell you what method I'm using.
The decimal equivalent of 3 divided by 11 is
0.2727272727... .
In order to be exactly equal to 3/11, the '27's must keep going forever, and never end.
If you don't have enough time or space on the paper to write an infinite string of '27's, then you can write some of them and then stop. The more '27's you write, the closer your decimal will be to 3/11 , so you can get it as close as you want. But if you ever stop, then it won't be exactly equal to 3/11 .
Normal curves are symmetrical. That means that on a standard normal distribution, the area less than -1.25 is the same as the area greater than +1.25. The total area under the curve is 1, so:
P = 1 - 0.894
P = 0.106
Approximately 10.6% of the area under the curve lies below -1.25.
