During the hottest week of the summer, the water level of the Muskrat river was 5/6 below normal. The following week, the level was 1/3 foot below normal. what is the overall change in the water level?


start at - 1/3 number line.


step 1 | find - 1/3 - (5/6)


step 2 | start at - 1/3


step 3 | move -5/6 = 5/6 to the right because ur subtracting a negative number.


the result is 1/2


so the water increased 1/2 foot.


now, compare the methods used to solve example 1 and 2.
