7/20 = 35%
A value of 35% might show up in everyday life as a discount on a jacket or the portion of a class that chose a certain activity. It means that 35% of the full amount is being described.
To picture 7/20 quickly, imagine 20 equal slices and shade 7 of them. It’s a little more than one-third, so you can estimate it as just above 33%.
One common mix-up is treating 35% as the amount left over rather than the amount being described. If 35% of a group chose an option, the remaining 65% did not choose it.
