Answer 2

To calculate the expression:

-1/21 * 11/13 * (-7/8) * (-26/55) * 60

You can follow these steps:

1. Multiply the fractions together: (-1/21) * (11/13) * (-7/8) * (-26/55)

2. Multiply the numerators together and the denominators together separately:

   Numerators: (-1) * (11) * (-7) * (-26) = 2002 Denominators: 21 * 13 * 8 * 55 = 251160

3. Now, divide the numerator by the denominator:

   2002 / 251160 = 1/125

4. Finally, multiply the result by 60:

   (1/125) * 60 = 60/125

You can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5:

(60/5) / (125/5) = 12/25

So, the simplified result of the expression is 12/25.
