When you change 43/67 to a percent you get 64.18%. This is the rounded value you would use in most everyday calculations, and it tells you that the fraction is a little more than six‑tenths of a whole.
The fraction 43/67 is already in its simplest form, because 43 and 67 share no common factors other than 1. It sits between 2/3 (≈66.67%) and 1/2 (50%), so the percentage makes sense as a middle‑ground value.
In real‑world situations, you might see this kind of number when dealing with test scores, survey results, or any data set where a part of a total is measured. Saying “the result is 64.18%” is clearer for most people than quoting the fraction.
If you need to compare it to other values, just remember that the percentage format is easier to read at a glance, while the fraction is useful for exact calculations or when you want to keep the numbers in their original form.
