Step-by-step explanation:
Step 1: Find the drop boxes
The first drop box, the leftmost, is 3 since we multiply it again by three to get nine. Therefore both the first and second drop boxes are 3.
Answer: Both 3
There is another way to do this problem which is cross multiply
[tex]\frac{x}{1.5} =\frac{9}{4.5}[/tex]
[tex]4.5(x) = 9(1.5)[/tex]
[tex]4.5x/4.5 = 13.5/4.5[/tex]
[tex]x = 3[/tex]
