Understanding percent increase and decrease

Percent increase and decrease asks learners to find a new value after a quantity grows or shrinks by a given percentage. Across Grades 6 and 7 this appears in prices, populations, and measurements, and it builds directly on finding a percent of a number. The key is to find the amount of change first, then add it for an increase or subtract it for a decrease.

To increase 80 by 25%, find 25% of 80, which is 20, then add to get 100; to decrease 80 by 25%, subtract the same 20 to get 60. A common mistake is to treat the percent as the answer itself, reporting 20 instead of the new total, or to add when the problem says decrease. A good tip is to read whether the value is rising or falling, compute the change as a percent of the original amount, and then combine it with the starting value in the correct direction.
