1:1/3

The expression \(1:1/3\) can be interpreted in a couple of ways depending on its context. If you're expressing a ratio, \(1:1/3\) can be interpreted as \(1\) compared to \(1/3\).

To simplify this ratio:

1. You can rewrite it as \(1 : \frac{1}{3}\).

2. To eliminate the fraction, you can multiply both sides of the ratio by \(3\), which gives you: \[ 1 \times 3 : \frac{1}{3} \times 3 = 3 : 1 \]

Thus, the ratio \(1:1/3\) simplifies to \(3:1\).
