The common denominator is 36: 23/36 - 12/36 = 11/36

both terms 23/36 and 1/3 need to have the same deniominator
so 23/36 - 1/3
=23/36 - 1*12/3*12
=23/36 - 12/36
=23-12 / 36
= 11/36

(23 / 36) - (1 / 3)
= (23 - 12) / 36
= 11 ./ 36

(23 / 36) - (1 / 3) [common denominator=36]
(23 / 36) - (12 / 36) [multiply (1 / 3) by 3 ]
= 11/ 36
check by:
1)key into the calculator 11 (divide sign) 36 and see if you get 0.305555556. [note:the last digit 6 is acutally rounded off as the original number is recurring]
2 ) add (12 / 36) to (11 / 36) = (23 / 36)

OK let us solve this question again
(23 / 36) - (1 / 3)
3*(23 / 36) - 36*(1 / 3)
(69 / 108) - (36 / 108)
(69 - 36) / 108
33 / 108
11 / 36 this the fraction that you asked for it in simplest form
11 / 36 = 0.305555556

(23 / 36) - (1 / 3)
= (( 3 * 23 ) / ( 3 * 36 )) - (( 36 * 1 ) / ( 36 * 3 ))
= ( 69 / 108 ) - ( 36 / 108 )
= 33 / 108
= 11 / 36

simplify the L.H.S
(23-12)/36 = 11/36 (L.C.M of 36 and 3 is 36)
verify by division.
