Question 1
Lets <em>convert these to decimals</em> first:
2 1/2 = 2.5
1/4 = 0.25
Now <em>divide</em> 2.5 by 0.25 to find how many scoops Zack uses.
If you divide correctly, you get <em>10</em>.
Now <em>multiply</em> this by two becuase Zack has TWO bird feeders.
So Zach uses <em>20 scoops</em> to fill both bird feeders.

Question 2
Let x be the variable for the scoops Zack needs for both bird feeders
x = 2 / x 2
------------------------------------------------------------------------------------------------------
Question 3
x = 2 / x 2
2 divided by = 10
x = 10 x2
10 multiplied by 2 is 20
So...
x = 20
