The water level of river is below normal levels. It's water level is 1 1/2 meters below sea level. During the summer the river drops another 2 1/3 meters below sea level. What is the water level at the end of the summer

1 answer

To find the water level at the end of the summer, we need to subtract the 2 1/3 meters that the river dropped from its already below normal level of 1 1/2 meters below sea level.

First, we need to convert the mixed number 1 1/2 to an improper fraction:
1 1/2 = (1 * 2 + 1)/2 = 3/2

Next, we need to convert the mixed number 2 1/3 to an improper fraction:
2 1/3 = (2 * 3 + 1)/3 = 7/3

Now, we can subtract the two fractions to find the final water level:
3/2 - 7/3 = (3 * 3 - 2 * 7)/(2 * 3) = (9 - 14)/6 = -5/6

Therefore, the water level at the end of the summer is 5/6 meters below sea level.
