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

Question 2
Let x be the variable for the scoops Zack needs for both bird feeders
x = 2 [tex]\frac{1}{2}[/tex] / [tex]\frac{1}{4}[/tex] x 2
------------------------------------------------------------------------------------------------------
Question 3
x = 2 [tex]\frac{1}{2}[/tex] / [tex]\frac{1}{4}[/tex] x 2
2 [tex]\frac{1}{2}[/tex] divided by [tex]\frac{1}{4}[/tex] = 10
x = 10 x2
10 multiplied by 2 is 20
So...
x = 20
