Your bird feeder holds 3⁄4 quarts of birdseed. Your scoop holds 3⁄8 of a cup. How many scoops of birdseed will fill the feeder?

First, let's create an equation for this problem. 
[tex] \frac{3}{4} [/tex] ÷ [tex] \frac{3}{8} [/tex]

Next, since you are dividing, you would flip the second fraction and change it to multiplication. 
[tex] \frac{3}{4} [/tex] × [tex] \frac{8}{3} [/tex]

Now, you would cross simplify it (you can also do this at the end instead, but this way is easier).
[tex] \frac{1}{1} [/tex] × [tex] \frac{2}{1} [/tex] 

The last step would be to solve it. 
[tex] \frac{1}{1} [/tex] × [tex] \frac{2}{1} [/tex]  = [tex] \frac{2}{1} [/tex] = 2

You would need 2 scoops of birdseed to fill the feeder. 

I hope this helps!
