70/80 = 87.5%
A value of 87.5% might describe a quiz score, a phone battery level, or how much of a project is finished. For example, getting 70 of 80 questions right means you did very well, even though you didn’t get every question correct.
To picture 70/80 quickly, think of a bar that’s nearly full, with just a small section left over. It’s a little less than 9 out of every 10 parts.
One common mix-up is treating 87.5% as the same as 87%, even though that half-percent can matter in precise scores or measurements. Also, 70/80 is not 70%: the 70 counts the parts you have, while 80 is the total.
