As a fraction, Tim planted of the trees.
WE cannot simplify that fraction,
and we cannot write it as a fraction with a for a denominator.
However, we can write a ratio, with a for a denominator,
that is approximately equal to .
If you divide by , you get .
The digits will eventually repeat, but it may take up to 105 digits before we see a repetition.
I would just approximate it as
.
That means that for every trees that were to be planted,
Tim planted about trees,
and that is the approximate percentage, .
To calculate a percentage,
you just divide to get the ratio as a decimal,
and then multiply times .
which rounds to ,
because is closer to than .
So, we say that Tim planted of the trees called for in the project.

NOTES:
A percentage is a ratio, which is sort-of a fraction.
If Joe had planted out of trees in a project,
he would have planted .
The fractions and are equivalent fractions.
We cannot call a fraction; we call it a ratio,
and we say that the ratios
, , and are the same.
They are equal, they are equivalent.
In that case we would say that out of is ,
and if we had to round ti whole numbers, we would sat it's ,
because is a s close to as it is to ,
but the usual custom is to always round up in those cases.
{if you have to get rid of a bunch of digits to round,
you look art the first digit you are discarding.
If it is 5 or more , you round up,
otherwise you round down>
So, rounds down to , but , and round up to .
(If the first digit after the decimal point is not 5 or more,
you just get rid of all digits after the decimal point,
and leave the as is.
Otherwise you up the to ).
