2/9+1/2-7/8+5/6=49/72

Explanation:

To simplify 2/9+1/2-7/8+5/6, we should first make all denominators equal. For this, we ought to know Least Common Denominator (LCD) of {9,2,8,6}, which is 72.

Hence, 2/9+1/2-7/8+5/6

= (2xx8)/(9xx8)+(1xx36)/(2xx36)-(7xx9)/(8xx9)+(5xx12)/(6xx12)

= 16/72+36/72-63/72+60/72

= (16+36-63+60)/72

= 49/72
