Answer 2

20:(69/11+19/11)+(37/5-29/5)*1/5=20:8+8/5*1/5=2,5+8/25=5/2+8/25=2,82

Answer 3

To find the value of the expression, let's follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

Step 1: Simplify the expressions inside the parentheses.

• For the first set of parentheses: 6 3/11 + 1 8/11 = 7 11/11 = 8 (since 11/11 is equal to 1)

• For the second set of parentheses: 7 2/5 - 5.8 = 7.4 - 5.8 = 1.6

Step 2: Now we have the expression: 20:(8 + 1.6) = 20 / 9.6

Step 3: Perform the division: 20 / 9.6 ≈ 2.0833 (rounded to four decimal places)

Therefore, the value of the expression is approximately 2.0833.
