Let's denote the unknown number as \( x \). According to the information provided:
\[ \frac{1}{3}x \times 8 = 37 \]
We can simplify this equation:
\[ \frac{8}{3}x = 37 \]
To isolate \( x \), we can multiply both sides by \( \frac{3}{8} \):
\[ x = 37 \times \frac{3}{8} \]
Calculating the right side:
\[ x = \frac{111}{8} \]
Now, performing the division:
\[ x = 13.875 \]
So, the number is \( 13.875 \).
