ok normally u just put the number after the decimal over 9

eg 0.3...
=3/9
=1/3

if there are 2 or more numbers being repeated u put them over 9 as well for however many numbers repeated

0.4545454545...
=45/99
(2 number r repeated)

but if u had a normal number followed by a repeating number u first split it up into a additon number sentence

0.123232323...
=0.1+0.023232323...

convert them into fractions

1/10 + 23/990
(in 23/990 the zero must be included coz the 0.23... is in the thousandth position but not quite, applies to all)

then add them

=61/495

continuing from ploygons a convex ploygon is a ploygon where all of its diagonals (a line from 1 corner of a shape to the oppisite corner) lie inside the ploygon. a convex ploygon also has no interior angle greater than 180 degrees.
