3/40 = 7.5%
A value like 7.5% can show up as a small sales tax, a discount, or the share of people who choose a particular option in a survey. It’s a modest amount, but it can still matter when the total is large.
To picture it quickly, think of 7 or 8 people out of every 100. It’s a little less than one-tenth, so it’s more than 5% but not quite 10%.
A common mistake is to read 7.5% as 75%, especially when scanning a chart or label quickly. The decimal point makes a big difference, so check it before comparing values.
