Answer 2

Let's solve each of these mathematical expressions step by step:

A) 2 × (-25): Multiplying a positive number by a negative number results in a negative number. 2 × (-25) = -50

B) 0 ÷ (-6 5/8): Division by any non-zero number divided by zero is undefined. In this case, you cannot divide by zero, so the expression is undefined.

C) (-3/4) ÷ (-1 1/2): To divide by a mixed number, you can first convert it to an improper fraction. (-1 1/2) = -3/2

Now, you can divide the fractions: (-3/4) ÷ (-3/2)

When dividing fractions, you can multiply by the reciprocal of the second fraction (invert and change the division sign to multiplication): (-3/4) × (-2/3)

Now, multiply the numerators and denominators separately: (-3 × -2) / (4 × 3) = 6/12

Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (which is 6): (6 ÷ 6) / (12 ÷ 6) = 1/2

So, the result of C) is 1/2.
