To find the overall change in water level for the last three years, we need to sum up all the changes in water level.
Year 1: -1 1/4 inches
Year 2: +3/4 inches
Year 3: -1 inch
To add these values together, let's convert the fractions to a common denominator. The common denominator of 4 and 1 is 4.
Year 1: -1 1/4 inches = -5/4 inches
Year 2: +3/4 inches
Year 3: -1 inch
Now, add the values together:
(-5/4) + (3/4) + (-1) = (-5 + 3 - 4)/4 = -6/4 = -1 1/2
Therefore, the overall change in water level for the last three years is -1 1/2 inches.
The table shows the average change in the water level of a reservoir for the last three years.
A negative number is a decrease in water level.
Annual change in water level (inches)
year 1 : -1 1/4
year 2 : +3/4
year 3 : -1
what is the overall change in water level for the last 3 years
