45/100 = 45%
A value like 45/100, or 45%, can show up in everyday life when 45 out of 100 students choose a certain lunch, a phone battery is nearly halfway charged, or a store offers a discount. It describes a portion that is less than half but still fairly close to it.
To picture 45%, imagine a grid with 100 small squares and shade 45 of them. A quick estimate is that it is just under one-half, since one-half would be 50%.
A common mistake is treating 45% as if it were 45 whole items instead of 45 out of every 100. The actual number depends on the total amount, so 45% of 20 is much smaller than 45% of 1,000.
