Lily is making granola. she uses almonds, walnuts, and pecans in the ratio 4 : 3 : 8. lily uses 40 ounces of pecans. a) find the weight of the walnuts. b) find the total weight of the granola

Almonds: 20
Walnuts:
Pecans:40

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



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.

8x= 40 x=5 4 x 5= 20 ounces almonds 3 x 5 = 15 ounces walnuts total weight= 75 ounces hope this helps
