Answer 2

To calculate the expression:

-3/7 * (2/3) * 2 1/3 * (-2 1/4)

First, let's simplify each part of the expression separately and then perform the calculations step by step.

1. -3/7 * (2/3): Multiply the fractions: (-3/7) * (2/3) = (-6/21) = (-2/7)

2. 2 1/3 * (-2 1/4): Convert the mixed numbers to improper fractions: 2 1/3 = 7/3 -2 1/4 = -9/4

   Now, multiply the fractions: (7/3) * (-9/4) = (-63/12) = (-21/4)

Now, combine the results:

(-2/7) * (-21/4)

To multiply fractions, simply multiply the numerators and denominators:

(-2/7) * (-21/4) = (2 * 21) / (7 * 4) = 42/28

Now, simplify the fraction:

42/28 = 3/2

So, the final result of the expression is 3/2.
