22 over 7 space i s space o f space t h e space f o r m space p over q comma space w h e r e space q not equal to 0 space a n d space h e n c e space i t space i s space r a t i o n a l. B u t space straight pi equals 3.1415923..... Here space the space digits space are space not space repeating space and space are space not space recurring space also. 22 over 7 space is space the space approximate space value space of space straight pi space and space it space is space not space exactly space equal space to space pi.
