(-324)*(-50) = 16200

(-4,7)*(-11) = 51,7

Answer 2

Let's calculate the expressions step by step:

1. (-14/15) * (-5/7) To multiply two fractions, multiply their numerators and denominators separately: Numerator: (-14) * (-5) = 70 Denominator: (15) * (7) = 105 The result is 70/105, which can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 35: Simplified result: 2/3

2. (-324) * (-50) When multiplying two negative numbers, the result is positive: (-324) * (-50) = 16,200

3. (-4.7) * (-11) When multiplying two negative numbers, the result is positive: (-4.7) * (-11) = 51.7

So, the results of the expressions are:

1. (-14/15) * (-5/7) = 2/3
2. (-324) * (-50) = 16,200
3. (-4.7) * (-11) = 51.7
