Question

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!!!!

Answer 1

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

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

Now go to school...lol

Answer 2

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: $\frac{120}{4}$  
This represents that they drink 120 gallons for every 4 days.

Now for what we're looking for: $\frac{x}{28}$
The x represents how how many days 

Now we just compare fractions: $\frac{120}{4}$ = $\frac{x}{28}$

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,  $\frac{120}{4}$ = $\frac{840}{28}$

Hope this helped!! :)
