81 servings. I found this by making a ratio:
24 c 108 c
------- = -------
18 ser x
I then cross multiplied to get the equation: 24x=1,944. I solved this equation to find x, the number of servings in 108 cups, which was 81.
I remember doing this back in elementary school. I had a hard time with it too!
Answer:
Step-by-step explanation:
Time taken to drive to work = 1 hr
Time taken to drive home = 1 hr
Time taken to drive from home to work and back home again ( IN ONE DAY)
=1 + 1 = 2hrs
So time taken for driving to and from work for 5 days = 2hrs × 5 days = 10 hrs .
A:b = 8:5 b:c = 3:4
since both sides have b. make b the same. multiply the left by the right side b value of 3 and multiply the right by the left side b value of 5.
3(a:b) and 5(b:c)
3 (8:5) and 5(3:4)
24:15 15:20
now that both sides have the same b value
a:b:c = 24:15:20
