Answer 1

Решение в вложении ниже

Answer 2

(1 24/25:(-1,4)+(-2 4/9):(-11/18))*5/13=1

1) (1 24/25):(-1,4)=(49/25)÷(14/10)=(49/25)*(10/14)=7/5=-1,4

2) (-2 4/9):(-11/18)=(-22/9)*(-18/11)=4

3) -1,4+4=2,6=26/10

4) (26/10)*(5/13)=1

Answer 3

Let's break down the expression step by step:

1. Simplify the fractions within parentheses:

(-1,4) = -1 + 4/9 (converting mixed number to an improper fraction) = -9/9 + 4/9 = -5/9

(-2 4/9) = -2 + 4/9 = -18/9 + 4/9 = -14/9

2. Perform the divisions within parentheses:

(-5/9) / (-14/9) = (-5/9) * (-9/14) (invert the divisor and multiply) = 45/126 = 5/14

3. Multiply the result by 5/13:

(5/14) * (5/13) = 25/182

Therefore, the final result of the expression (1 24/25: (-1,4) + (-2 4/9): (-11/18)) * 5/13 is 25/182.
