Respuesta :

x = ((1200) / (0.5525) = 2,179.94570

Answer:

The unknown number is [tex]2171\frac{209}{221}[/tex].

Step-by-step explanation:

Let the unknown number is x

Now we will write the equation to get the value of x.

[tex]55\frac{1}{4}[/tex]% of x = 1200

[tex]\frac{221}{4}[/tex]% of x = 1200

[tex]\frac{221x}{400}=1200[/tex]

[tex]x=\frac{1200\times 400}{221}[/tex] [By cross multiplication]

x = [tex]\frac{480000}{221}[/tex]

[tex]x=2171\frac{209}{221}[/tex]

Therefore, the unknown number is [tex]2171\frac{209}{221}[/tex]
