7/10 = 70%
A value of 7/10, or 70%, shows up often in everyday life. For example, a weather forecast might say there is a 70% chance of rain, or a student might earn 7 out of 10 points on a quiz.
To picture 7/10 quickly, imagine a row of 10 equal boxes with 7 shaded in. It is more than half but less than the whole, so you can estimate it as about three-quarters.
A common mistake is thinking 70% means 70 out of 100 separate items in every situation. It represents the same proportion as 7 out of 10, even when the total amount is different.
