Find the lowest common denominator:
8-3/10 + 2/15
= 8/1 - 3/10 +2/15
= 240/30 - 9/30 + 4/30
= 235/30
= 47/6
= 7 5/6 or 7.83

8/1 - 3/10 + 2/15. The common denominator between 1,10, and 15 is 30. So,
240/30 - 9/30 + 4/30 = 235/30 = 47/6 = 7.833 = 7 5/6

8-3/10 + 2/15
=8*10*15/10/15 -3*15/10/15 +2*10/15/10
=1200/10/15 -45/10/15+20/10/15
=(1200-45+20)/10/15
=1175/10/15
=47/6
=7+5/6
