300.
Steps:
27x100 = 2700
12x300=3600
3600+2700=6300
I would convert them all to the denominator 16, due to the smallest fraction and all of them can be converted to it.
1 = 16/16
1/2 = 8/16
1/4 = 4/16
1/8 = 2/16
1/16 = 1/16
1+ 2 + 4 + 8 + 16 = 31
31/16 = 1 15/16
Hope this helps!
The quadratic that has the roots x=8 and x=-5 is
x^2-3x-40
Hope this helps you! (:
