21/2-35/6=63/6-35/6=28/6=4 4/6=

4 2/3

Answer 2

To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression you provided is:

3:33/4 + 22/5 - 21/2 - 35/6

First, let's convert 3:33 to a fraction of hours:

3 hours and 33 minutes = 3 + 33/60 = 3 + 11/20 = 63/20 hours

Now, the expression becomes:

63/20 + 22/5 - 21/2 - 35/6

Next, find a common denominator for the fractions:

The common denominator for 20, 5, and 2 is 20, so we need to rewrite each fraction:

63/20 + (22/5) * (4/4) - (21/2) * (10/10) - (35/6) * (10/10)

Now, the expression becomes:

63/20 + 88/20 - 105/20 - 350/60

Now that all fractions have the same denominator, we can perform the addition and subtraction:

(63 + 88 - 105 - 350) / 20

Now, calculate the numerator:

(63 + 88 - 105 - 350) = -304

So, the expression becomes:

-304 / 20

Finally, simplify the fraction:

-304 divided by 20 is equal to -15.2

Therefore, the final result is:

-15.2
