1)a)5x/6a + 2x/6a= 7x/6a
b)4/9a + 1/9a = 4+1/9a= 5/9a
c)4x/3y - x/3y = 3x/3y= x/y
d)2x/a +8x/a= 10x/a
e)2x-3y/3a+ 3x+4y/3a= 2x-3y+3x+4y/4a= 5x+y/3a
f)5x/8m + 2x-9/8m = 5x+2x-9/8m= 7x-9/8m
b)4/9a + 1/9a = 4+1/9a= 5/9a
c)4x/3y - x/3y = 3x/3y= x/y
d)2x/a +8x/a= 10x/a
e)2x-3y/3a+ 3x+4y/3a= 2x-3y+3x+4y/4a= 5x+y/3a
f)5x/8m + 2x-9/8m = 5x+2x-9/8m= 7x-9/8m
