Explanation:

Step1: Understand the ratio

The given ratio is \(5:4\). Another way to represent a ratio is as a fraction or a decimal (or by scaling both parts by a common factor). Let's scale it by 2.

Step2: Scale the ratio

To scale the ratio \(5:4\) by 2, we multiply both parts by 2. So, \(5\times2 = 10\) and \(4\times2 = 8\). So the ratio can also be written as \(10:8\). (Or as a fraction \(\frac{5}{4}=1.25\), but if we follow the example format which seems to be an integer, scaling by 2 gives \(10:8\) or just showing the fraction as \( \frac{5}{4}\) or decimal \(1.25\). But from the example input "2", maybe they want an equivalent ratio by multiplying numerator and denominator by a number. Let's take multiplying by 2: \(5\times2 = 10\), \(4\times2 = 8\), so \(10:8\) or if we consider the example "2" as a multiplier, then \(5\times2 = 10\), so the answer could be 10 (if we take the first part of the ratio scaled by 2).

Answer:

10 (or \(10:8\) or \(1.25\), depending on interpretation. Since the example has "2" as input, likely scaling the first term of the ratio \(5:4\) by 2 gives \(10\))
