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