An easy way to find simplest form is to divide each part of the fraction by a common factor until there is no more common factor (that is till they don't share a factor) (for quickest results use the Highest Common Factor).
In this case the highest common factor (and the only common factor (barring 1 which will not achieve anything)) is 2.
46/2 = 23
200/2 = 100
There are no more common factors so the simplest form is: 23/100
35/46 is in its simplest form.
46/47 is in its simplest form.
9/46 is already in simplest form.
16/23 is its simplest form
44/46 = 22/23
13/46 is in its simplest form
21/46 is the simplest form.
35/46 is in its simplest form.
46/47 is in its simplest form.
9/46 is already in simplest form.
22/46 in simplest form is 11/23
43/46 is in its simplest form.
16/23 is its simplest form
33/46 is already simplified.
46/18 = 25/9
It is: 46/66 = 23/33
46/66 = 23/33
