You don't. You can only write numbers greater than one as a mixed number.
(3x4+5+6+7)/10=3
(3*3 + 3)/3 + 3
3 x 3 x 3 + 3 + 3 + ( 3 / 3 ) or 33 + ( 3 / 3 )
A number can only contain 1 decimal.
3 - 4 + 5 * 6 + 7 > 10
Divide 7 by 3, using integer division. Write the result (which must be an integer) as the whole number. Write the remainder as the numerator, over the number 3 which is the denominator.

There is no largest number. You can just keep going.
3 x 3 + 3 + (3+3)/3
18

It is done by using Roman numerals: VI = 6
33+3+3/3 = 31
31 = 33 + 3 + 3/3
