    What do you mean by "verifying" a number? Are you perhaps supposed to "simplify" the expression?

    When you reply, please show us what you've tried so far. Thank you!

    What have YOU done? Basically asking you to verify the "associative property of multiplication".
    On the left you are supposed to first multiply -12/7 by 31/32. What do you get for that? Now multiply that by -13/24.
    On the right you are supposed to first multiply -13/24 by -12/7. What do you get for that? Now multiply that b7 31/32.

    Do you get the same result?
