F:m:s=4:5:7

s=f+18 and from above we see s/f=7/4 so s=7f/4 now we can say:

f+18=7f/4

4f+72=7f

3f=72

f=24 and we know s=f+18 so

s=42

m/s=5/7 so m=42*5/7=30

So Frank got 24, Mary got 30, and Seth got 42.

kylie drank 35% of 400-mL container of water.Eugenia drank 45% of a 350-mL.Who drank more water?How do you know? I will have mor
GREYUIT [131]
In the question, there are two people with different percentage of drinking water from different quantities.
Taking the first case of Kylie we get that he drank 35% water of 400ml
Then
35% of 400 ml = (35/100) * 400 ml
                         = (35 * 4) ml
                         = 140 ml
So Kylie drank a total of 140 ml water.
Now taking the case of Eugenia we get that he drank 45% of 350 ml water.
Then
45% of 350 ml = (45/100) * 350
                         = 1575/10 ml
                         = 157.5 ml
So Eugenia drank 157.5 ml of water. Then we can conclude that Eugenia drank more water than Kylie.
