Almonds: 20
Walnuts:
Pecans:40

Since the ratios are 4,3, and 8, the best way to do it is to use a proportion.

$\frac{40}{8} = \frac{x}{3}$

So yeah what you do it cross multiply and get 120=8x
divide by 8 and get 15.
15 ounces of walnuts.

Now for total just find the last part.
Since 4 is half of 8, the number of ounces is half of 40, which is 20.
So 20+40+15? You guessed it 75 ounces of Granola.

Hope that made sense.
