A Clydesdale drinks about 120 gallons of water every 4 days, at this rate, about how many gallons of water will he drink in 28 days

HELP PLEASE I'm stuck on this question and need to go to school soon!!!!

Respuesta :

120 gallons in 4 days.....120/4 = 30 gallons per day

for 28 days...
30 * 28 = 840 gallons <==

Now go to school...lol
The answer is 840 gallons

To get this answer, it is easiest if we set it up as a fraction. 

We can write this to represent how much we know Clydesdale drinks: [tex] \frac{120}{4} [/tex]  
This represents that they drink 120 gallons for every 4 days.

Now for what we're looking for: [tex] \frac{x}{28} [/tex]
The x represents how how many days 

Now we just compare fractions: [tex] \frac{120}{4} [/tex] = [tex] \frac{x}{28} [/tex]

If we look at the denominators, 4 is multiplied by 7 to get 28, so to find our missing numerator, we multiply 120 by 7, which gives us our answer: 840

So,  [tex] \frac{120}{4} [/tex] = [tex] \frac{840}{28} [/tex]

Hope this helped!! :)
