8-3 3/7

 

Simplify the following:
8-(3+3/7)

Put 3+3/7 over the common denominator 7. 3+3/7  =  (7×3)/7+3/7:
8-(7×3)/7+3/7

7×3  =  21:
8-(21/7+3/7)

21/7+3/7  =  (21+3)/7:
8-(21+3)/7

21+3 = 24:
8-24/7

Put 8-24/7 over the common denominator 7. 8-24/7  =  (7×8)/7-24/7:
(7×8)/7-24/7

7×8  =  56:
56/7-24/7

56/7-(24)/7  =  (56-24)/7:
