Answer 2

To simplify the expression, let's convert the mixed numbers to improper fractions and then perform the division:

First, let's convert the mixed numbers to improper fractions: 3 6/1 = (3 * 1 + 6) / 1 = 9/1 2 5/1 = (2 * 1 + 5) / 1 = 7/1 1 6/5 = (1 * 5 + 6) / 5 = 11/5 2 15/1 = (2 * 1 + 15) / 1 = 17/1

Now, let's substitute these values back into the expression: (9/1 - 4 3/1 * 7/1) / (11/5 - 17/1)

Next, let's simplify the multiplication: 4 3/1 * 7/1 = (4 * 1 + 3) / 1 * 7/1 = 7/1 * 7/1 = 49/1

Now, let's simplify the subtraction: 9/1 - 49/1 = (9 - 49) / 1 = -40/1 = -40

Similarly, let's simplify the subtraction in the denominator: 11/5 - 17/1 = (11 - (17 * 5)) / 5 = (11 - 85) / 5 = -74/5

Finally, let's perform the division: (-40) / (-74/5) = (-40) * (5/(-74)) = (-40 * 5) / (-74) = -200/(-74)

To simplify further, we can divide both the numerator and denominator by their greatest common divisor, which is 2: -200/(-74) = 100/37

Therefore, the expression (3,6-4 3/1*2,5):(1 6/5-2 15/1) simplifies to 100/37.
