2/4 as a percentage is 50.00%. This means that the fraction represents exactly half of a whole. When you see 2 out of 4 parts, you are looking at a 50‑percent share.
The fraction 2/4 can be simplified to 1/2, which is another common way to show the same value. Both 2/4 and 1/2 describe the same portion of a whole, just written differently.
In everyday situations, saying “50 %” is often clearer than using the fraction. Whether you’re splitting a pizza, dividing a budget, or measuring a test score, the idea stays the same: half of the total.
