To solve the problem, we assume a linear relationship between the two values. Given that:

- When a certain unknown value is 147.2, the result is 15.

Let’s denote the proportional relationship as follows:

\[
\frac{147.2}{15} = \frac{146}{x}
\]

We can now solve for \( x \), the result when the value is 146.

\[
x = \frac{146 \times 15}{147.2}
\]

Let me calculate this.The result when the value is 146 is approximately \( 14.88 \).
