6/75 = 8%
A value like 8% can show up as a discount on a store item, a small fee, or the share of people who choose a certain option in a survey. It describes a small part of a whole, but it can still matter when the total is large.
To picture it quickly, imagine 8 shaded squares in a grid of 100, or a little less than 1 out of every 10 items. That makes it easier to judge whether an amount seems close to this share.
A common mix-up is treating 8% as 8 out of 10 rather than 8 out of 100. Also, 8% of a small amount is small, but 8% of a large amount can be quite noticeable.
