55/400 = 13.75%
The fraction 55/400 could describe a survey where 55 out of 400 people choose the same answer. That amount, 13.75%, might also show up as the share of products on sale, students absent, or customers who prefer one option.
To picture 55/400 quickly, think of a group of 400 split into 100 equal-sized parts, with about 14 of those parts highlighted. It is a little more than one-eighth, since one-eighth is 12.5%.
A common mistake is rounding 13.75% to 14% and then treating the rounded value as exact. Another point of confusion is thinking 55/400 means 55%, when the denominator shows that 55 is being compared with 400.
