Answer:The answer is 24/2=36/3=66/5.5=108/9=180/15.Step-by-step explanation:Given:24/2=_/3=_/5.5=108/_=_/15.Now, we need to solve this by putting [tex]x[/tex] in the place of _ and then continue:[tex]\frac{24}{2} =\frac{x}{3}[/tex]By cross multiplication we get:[tex]72=2x[/tex]By dividing with 2 we get:[tex]36=x[/tex]Now, we will continue like this process:[tex]\frac{36}{3}=\frac{x}{5.5}[/tex][tex]198=3x[/tex][tex]x=66[/tex]And, then again:[tex]\frac{66}{5.5}=\frac{108}{x}[/tex][tex]66x=594[/tex][tex]x=9[/tex]And, last:[tex]\frac{108}{9}=\frac{x}{15}[/tex][tex]9x=1620[/tex][tex]x=180[/tex]Therefore, the answer is 24/2=36/3=66/5.5=108/9=180/15.
