Mark's balance in the account would be -$11 + (-$25) = -$36.

1 1/2 2 1/3

To add the numbers 1 1/2 and 2 1/3, we first need to convert them to improper fractions.

1 1/2 can be written as 3/2.
2 1/3 can be written as 7/3.

Now we can add them together:
3/2 + 7/3 = (9/6) + (14/6) = 23/6.

So, 1 1/2 + 2 1/3 = 23/6.

The water level of a river is below normal levels it's water level is at one and a half meters below sea level during the summer the rain river drops another two 1/3 meters below sea level what is the water level at at the end of summer

To find the water level at the end of summer, we need to add one and a half meters below sea level with another two and a third meters below sea level.

First, let's convert one and a half meters to a mixed number: 1 1/2 = 3/2.

Now let's convert two and a third meters to an improper fraction: 2 1/3 = 7/3.

Now we can add the fractions:
3/2 + 7/3.

To add these fractions, we need to find a common denominator, which in this case is 6.

Multiply the numerator and denominator of the first fraction by 3:
(3/2) * (3/3) = 9/6.

Multiply the numerator and denominator of the second fraction by 2:
(7/3) * (2/2) = 14/6.

Now we can add the fractions:
9/6 + 14/6 = 23/6.

Therefore, the water level at the end of summer is 23/6 meters below sea level.

To find the balance in Mark's checking account after the $25 fee is charged, you need to add the fee to the existing balance.

The existing balance is -$11. Adding the $25 fee to the existing balance gives us:

-$11 + $25 = $14

Therefore, the balance in Mark's account after the fee is charged is $14.

To determine the balance in Mark's account after the bank charged a fee, you need to subtract the fee amount from the existing balance. Here's how you can calculate it:

1. Start with the existing balance: -$11
2. Subtract the fee amount: -$11 - $25 = -$36

Therefore, the balance in Mark's account after the bank charged the $25 fee is -$36. Note that a negative balance indicates that Mark owes money to the bank.
