Answer 2

Answer:

The missing value is 255.

Step-by-step explanation:

The given ratios are

$75:45::125:75::50:30::425:\_\_\_$

Let the missing value be x.

$75:45::125:75::50:30::425:x$

$\frac{75}{45}=\frac{125}{75}=\frac{50}{30}=\frac{425}{x}$

Rewrite all ratios in a simplified form.

$\frac{5}{3}=\frac{5}{3}=\frac{5}{3}=\frac{425}{x}$

So,

$\frac{5}{3}=\frac{425}{x}$

$5x=425\times 3$

$5x=1275$

Divide both side by 5.

$x=\frac{1275}{5}$

$x=255$

Therefore the missing value is 255.
