12/100 = 12%
A value of 12/100, or 12%, can show up as a sales tax, a discount, or the share of people in a group who chose a certain option. For example, if 12 out of 100 students ride the bus, that’s a 12% share.
To picture 12% quickly, imagine 12 shaded squares on a grid of 100 squares. It’s a little more than one-tenth, so it’s noticeably larger than 10% but still a small part of the whole.
A common mix-up is confusing 12% with 12 percentage points. A change from 10% to 12% is an increase of 2 percentage points, not a 12-point increase.
