Answer 2

(13/3-11/5)*(-0,1875)-61/20
32/15(-3/16)-61/20
-2/5-61/20=
-69/20=
-3 9/20 =
-3,45

Answer 3

To simplify the expression, let's first convert the mixed number 4 1/3 to an improper fraction:

4 1/3 = (4 * 3 + 1) / 3 = 13/3

Now we can substitute the values into the expression:

(13/3 - 2.2) * (-3/16) - 3.05

Next, let's perform the arithmetic:

(13/3 - 2.2) = (13/3 - 6/3) = 7/3

(-3/16) * (7/3) = (-3 * 7) / (16 * 3) = -21/48

Now, we have:

-21/48 - 3.05

To combine the fractions with the decimal, we need a common denominator:

-21/48 = -105/240

Now, let's subtract:

-105/240 - 3.05 = (-105 - 240 * 3.05) / 240

= (-105 - 732) / 240

= -837 / 240

This fraction can be simplified by dividing the numerator and denominator by their greatest common divisor (GCD), which is 3:

-837 / 240 = (-837 ÷ 3) / (240 ÷ 3) = -279 / 80

Therefore, the simplified expression is -279/80.
