<PRE><B>Question 334122</B>
Find the sum: 8/15 + (-2/3) = (8/15)-(10/15) = -2/15
---------------------------------------------------------
Find the sum: -3 1/4 + (-2 2/5) = (-13/4)-(12/5) 
= (-65/20)-(48/20) = -113/20
--------------------------------------------------------- 
Find the difference: 5/8 - 3/4 = (5/8)-(6/8) = -1/8
---------------------------------------------------------
Find the difference: -4/10 - (-1/6) = (-12/30)+(5/30) = -7/30
---------------------------------------------------------
Find the difference: -6 2/3 - 4 3/5 = (-20/3)-(23/5)
= (-100/15)-(69/15)
= -169/15
