Easy,
the Pythagorean theorem is:
The a and b, being a value that you HAVE
and
c, being the value you are trying to find.
Example: have 1,2 for a triangle what is the third side?
1+4=
5=
Then, just square root to find c.
=c
2.2≈c

1) To write 0.259 as a fraction let's firstly rewrite as
2) Count the digits the dot has gone to the left. Each digit to the left means divided by ten. Like this:
3) Since it starts with a zero then it can't be a Mixed number. So it is an improper fraction. No further simplification could be done.
