Answer 1

Hi there!

To solve both of you questions, you will need to use the cross product method :

Finding "x" :

$\frac{2scoops}{1/2gallon} = \frac{4scoops}{xgallon}$

So you have to do :

(4 × $\frac{1}{2}$) ÷ 2 = x gallon

4 times $\frac{1}{2}$ is the same thing as 4 times 0.5, which equals 2.

2 ÷ 2 = x gallon

1 = x gallon

So the amout for x would be : 1 gallon

Finding "y" :

You could do the exact same method as we did for finding "x", but the easiest and fastest way to get our answer is just by multiplying the amout we got for "x" by 2 because we are putting 8 scoops instead of 4 for "x" (and 4 times 2 = 8) :

1 gallon × 2 = y

2 gallons = y

So your answer is : The amount for y would be : 2 gallons

There you go! I really hope this helped, if there's anything just let me know! :)
