Answer:

0.84

Explanation:

To find the value of
that makes the ratio 7.4 : 0.5 equivalent to 12.4 :
, we can set up a proportion:

(7.4)/(0.5) = (12.4)/(x)

Cross-multiply:

$7.4 \cdot x = 0.5 \cdot 12.4$

Simplify both sides:

7.4x = 6.2

Now, solve for
by dividing both sides by 7.4:

x = (6.2)/(7.4)

x=0.837837837837...

$x=0.\overline{837}$

Therefore, the unknown value (
) is 0.84 when rounded to the nearest hundredth.
