Answer 1

А)-4 5/7:(-11/14)= -33/7 • (-14/11)= 6
б)-4,125:11/14= -4125/1000 • 14/11= -5250/1000= -5,25

Answer 2

А) To solve the expression -4 5/7 : (-11/14), we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

Step 1: Convert the mixed number -4 5/7 to an improper fraction: -4 5/7 = (-4 * 7 + 5) / 7 = (-28 + 5) / 7 = -23/7

Step 2: Rewrite the division as multiplication by the reciprocal: -23/7 : (-11/14) = -23/7 * (-14/11)

Step 3: Multiply the fractions: -23/7 * (-14/11) = (23 * 14) / (7 * 11) = 322/77

The result of -4 5/7 : (-11/14) is 322/77.

Б) To solve the expression -4,125 : 11/24, we again follow the order of operations:

Step 1: Rewrite the division as multiplication by the reciprocal: -4,125 : (11/24) = -4,125 * (24/11)

Step 2: Perform the multiplication: -4,125 * (24/11) = (-4,125 * 24) / 11 = -99,000 / 11

Step 3: Simplify the fraction if possible: -99,000 / 11 = -9,000

The result of -4,125 : 11/24 is -9,000.

Please note that it's important to be clear about the formatting of the numbers. In option Б, I assumed that the comma (",") represents a decimal separator. If it represents a thousands separator, please let me know, and I can adjust the calculation accordingly.
