6/30 = 20%
A fraction like 6/30, or 20%, can show up in everyday life when a store offers a discount, a survey reports how many people chose an option, or a recipe calls for a portion of an ingredient. It describes one part of a whole group or amount.
To picture 20% quickly, imagine a row of five equal boxes with one shaded in. That shaded box represents one-fifth of the whole, so it’s a handy way to estimate the amount without doing detailed arithmetic.
A common point of confusion is mixing up the number of parts with the size of each part. For example, 6/30 means six parts out of a total of thirty, not six parts out of twenty.
